FKA twigs lives in a real house, in the real world, though this seems hard to believe. She appears so alien, in her music and her performances, in the way she presents herself, that you’d be forgiven for believing that she lived in a cryo chamber alongside bejewelled hip-hop robots, or a martial arts monastery surrounded by an enchanted thicket of thorns.

Twigs’ art is not of the stripped-back, real me, acoustics-and-grubby-jeans variety. She arrived on the scene in 2012, whispering like Tricky, clattering like the xx, romancing like Prince, singing like Kate Bush, yet not actually quite like anyone else. A polymath – she is a beautiful dancer and has directed pop videos and immersive theatre – she works in experimental hinterlands, creating atmospheres rather than singalong stories. For example: the sparse and sad track Cellophane, released in April as the opening single for her new album, was accompanied by a video that featured twigs athletically pole-dancing in a sparkly bikini before being eaten by a lookalike insect, falling into watery depths and being covered in orange mud by caring tortoise creatures. Twigs is about intensity, beauty, sexuality and freakiness.

Because of this, I’ve geared myself up for her to be a tricky interviewee. Distant. Abstract. Maybe a bit defiant. But twigs is not like this. She is friendly and quite serious. She has a light, RP voice with a slight lisp and a young face; though she is now 31, she can seem 10 years younger, especially when she laughs.

We meet in her lovely home in east London. Her sitting room is olive green, with plants and a piano, fossils and tapestries and books about jazz. Preserved snakes twist under glass domes. There is a Diptyque Feu du Bois candle burning. The vibe is part museum of curiosities, part comfy boutique hotel. Her small dog, Solo, is lounging on the rug. “I found her in LA four years ago, behind a nail salon,” twigs says. “She was tiny, about six months old, and all alone.” (For the dog spotters: Solo enjoys chasing a ball and can do sit, paw and lie down. And, yes, she sleeps on twigs’ bed.)

Twigs thinks about how she presents herself. For this interview, she has dressed in an embroidered white shirt, Burberry shorts and white socks, with velvet ribbons at her throat. Her hair is partly dyed a wild red. Like the dancer she is, she’s poised but casual, plonking herself on the floor (all dancers sit on the floor). Sweetly, she has three types of posh juice for me to choose from, though she herself drinks herbal tea.

It’s taken her some time to sort her house out; for quite a while, she just had a sofa, a bed and a TV: “Very discombobulating,” she says. Before that, she’d been living in a rented house share, and didn’t have the money to furnish her new pad, though now she does (Nike appointed her creative director for a 2017 womenswear campaign, and she’s made an advert with Apple, so her money situation has improved). Anyway, even if she’d had the cash, she wouldn’t have been up for decorating; she has had a difficult couple of years.

It felt like I’d made this ornate golden birdcage. And I stepped in and was like, oh gosh, this is actually a nightmare

Though she didn’t make it public – and refuses to talk about it with me – in 2017 she split up with her long-term boyfriend Robert Pattinson, the Twilight Saga actor who’s set to be the next Batman. Their relationship had brought her tabloid scrutiny and weird fan abuse: Pattinson fans can be rabid, and racially trolled twigs on social media. After their split, she no longer had a home base in LA – plus she was ill (more about this later) and, most importantly for her, she was in an artistic fug.

She found the new album – Magdalene, her second – really hard to make, she says, mostly because she wanted to change but couldn’t figure out how. She began work on it as soon as she had finished her first, LP1, but couldn’t find the right sound, and couldn’t write songs in the way she wanted. Producers assumed she wanted to work with the fractured, futuristic noise of LP1 again and she felt trapped. Though she managed one song – Day Bed, which ends the album, and is about being depressed – she was stuck, workwise, in an artistry of her own making.

“I find it easy to write over complete musical randomness,” she says. “But that’s not what I wanted. I wanted something simpler, something honest. It felt like I’d made this ornate golden birdcage, and everything was so intricate – like tapestries and beading and beautiful wirework. And I stepped in and I locked the door and I was like, oh my gosh, this is actually a nightmare.”

Her process of breaking free ended up being pretty thorough. Her music altered, her relationship ended, her health went haywire. A disciplined workaholic, twigs sees life as a matter of spinning plates – “You have family and friends, and you have adult things, like where you live and bills and stuff like that, then your health, maybe your relationship” – and, for a while, around 2017, nearly all the plates dropped to the floor and smashed. “Everything was in complete turmoil,” she says. “The only thing that didn’t get smashed or shaken was one or two great friends.”

Things came to a head in LA, in just one week. She’d been searching for the right musical collaborator, and had found one in cult electronica artist Nicolas Jaar. They wrote Cellophane together in about 20 minutes, and she was thrilled. But she also felt physically terrible. She had a lump in her stomach that she’d been ignoring for months and one day that week, she woke and found she couldn’t sit up. She phoned her stepfather. “I said, ‘OK, I fucked up. I have some terrible thing in my stomach and it’s really big and I must have stomach cancer and I’ve not told anyone and I just don’t think there’s any coming back.’” Twigs says this all in rapid-fire full tragedy mode, rolling her eyes at herself. What did your stepfather say? “He said, ‘Go to the doctor.’”

An ultrasound scan revealed not cancer, but fibroids – hormonal growths on her uterus. Twigs’s were enormous – “Two cooking apples, three kiwis and a couple of strawberries: a fruit bowl of pain,” as she described them on Instagram – and she had laparoscopic surgery, back in the UK. “They went in through three or four entry points” – she points at her stomach – “and pulled out the fibroids, like a string of sausages, through my bellybutton.”

She had been in pain for a while; plus the fibroids had been pressing down on her bowel and bladder, making her want to pee all the time and giving her unpleasant IBS symptoms. She remembers working on a video before the operation. “I had to do voguing in it and the choreographers, these two women, weren’t very nice and said, ‘You’re really lazy and you keep going to the toilet all the time.’ My whole life, I’d never been called lazy. It made me break down.”

As if to prove how un-lazy she is, a few weeks after the operation she got a call from the director Spike Jonze. He wanted her to audition for an ad he was making for Apple’s HomePod. For the audition, she had to dance around this very room in front of her laptop, hoping her stitches wouldn’t split. “Then they said, ‘That’s great. Now can you do it again and, like, touch the objects in the room?’” She laughs. But being a pro – she had spent years as a dancer for hire – she did as they asked. “I was like, ‘Sure, from the beginning of the song or halfway through? No problem. You want it again, but in a crop top?’”

She’s joking, but both incidents indicate the same thing about her. Twigs is a worker. She moved to London from Cheltenham when she was 17 and spent a few years as a back-up dancer, hired to shimmy behind stars such as Ed Sheeran, Kylie Minogue and Jessie J. Even now that she’s an artist in her own right, she flips between being in charge, as a musician and director, and being directed, when she’s dancing. She’s more inclined to the former, though doesn’t mind being told what to do if she’s learning and she thinks the work is good. She likes collaboration, and “I have a good taste barometer”.

Anyhow, she wants to talk more about fibroids, because she had never heard of them until she got them, even though many women suffer with them, especially women of Caribbean origin (twigs is half Jamaican). She’s learned that they can be managed through stress management and diet: it’s important to avoid sugar and foods with oestrogen, she says – soy, dairy, non-organic meat. Also, receipts.

Receipts? I say, wondering if I’ve heard her wrong.

“Yes. The paper they use, the ink, there’s something about it that’s got a lot of oestrogen and you ingest it through your skin.”

Hmm, I say, but when I check later, I discover twigs is right: receipt ink contains BPA, an artificial oestrogen, which can be absorbed through contact. God, what a tricky thing. She also avoids tap water, because it has traces of the pill in it, and can’t use hormonal contraception: “I’m a believer in western medicine, but there are other ways, depending on how your body works.” She has been really careful, but still her fibroids grew back within three months. Now she has six more, which she is managing. “As soon as I had my operation, I felt so much better,” she says, “like all these trapped-up feelings were released. But I’ve never felt the same since. I’m different.”

She has thrown herself into getting immensely fit. She knew that she wanted to pole dance for the video for Cellophane and it took her six months of training to get strong enough to do it. She is a true athlete now: she has learned how to do an aerial cartwheel, she is proficient in a type of sword kung fu called wushu, which she’s been using in her live shows. She chose to learn this, she tells me, because it’s the opposite of pole dancing, very grounded and “weighted in the pelvis”, requiring her to use her legs. She is stronger than she’s ever been.

I do wonder about the pole dancing. She’s done it before, in the video for Fukk Sleep, an A$AP Rocky song she guested on, where it was more straightforwardly man-pleasing. But twigs has always explored her sexuality in her work and tells me, “My sexuality tank and my creativity tank are the same tank, which is great, but also quite frustrating.” If she’s feeling sexually confused or uninspired, then her work is off; but equally, if her work is good, then she feels strong and sexual. In the Cellophane video, she is unbelievably sexy, but her needy lyrics – “Didn’t I do it for you? Why don’t I do it for you?” – play against this.

“Well,” she says, “I think that, in society, as a woman, you can be this beautiful creature and you want to be that for yourself, but there’s also a part of you that is doing it for the approval of the opposite sex. And that can lead you to feeling, ‘Am I good enough? Have I done enough?’”

If it seems a bit extreme – twirling around a pole in the full splits position just to get a man to think you’re great – well, twigs has started asking questions about such things. She watched the great Kathy Burke TV series All Woman, which she loved, and she’s been noticing how women often do the “emotional labour” of a relationship, what she calls “learned behaviour”. To her chagrin, she is often referred to in terms of her boyfriends (since Pattinson, she’s been linked with another actor, Shia LaBeouf, and is dating Reuben Esser, fashion editor of Another Man magazine). It irritates her, but she is also conflicted about relationships in general.

“I feel like I’ve been indoctrinated to feel like when I’m with a man, things are better,” she says, “regardless of whether they are or not. I’ve been made to feel like, if I’m with a man, then I’m doing the right thing, I’m validated, I have a tick to my name. And even though I don’t really believe that, because I’m intelligent and I understand things, it’s somewhere inside me.”

Twigs grew up in Cheltenham as Tahliah Debrett Barnett, the only child of an English-Spanish single mother from Birmingham, who’d moved out to the countryside to give her daughter a better life. And it was, twigs says; she loved being outside, she enjoyed nature. The walls and ceilings of her room were painted dark blue, with stars and moons on them.

As a child, she had a great imagination – “It was on fleek!” she says – and often mixed up daydreams and reality: until she was about 12, she sort of believed she could fly and hang in the air, simply by jumping off the stairs. Clever and hard-working, she got a scholarship to a private all-girls Catholic secondary school, which she enjoyed while feeling entirely different from everyone else. There were no other mixed-race students. Her stepfather, who moved in when she was little, was one of the few black people in her life. When he gave lifts to her friends, she was embarrassed by the music he played in the car: acid jazz, real jazz, Fela Kuti, Nina Simone. She would ask him to play the radio instead, though he never did.

My mother would pump me up and I’d be like, 'Yes, I am pretty', then go to the school disco and want the floor to eat me

Her mother took pains to make her feel beautiful, telling her her hair was lovely and her skin colour was gorgeous, but she didn’t feel it. “She’d pump me up at home and I’d be like, ‘Yes, I am pretty’ and I’d get dressed up and think, ‘Yes, I feel good.’ And then I’d go to the school disco and as soon as I got there I’d want the floor to eat me, because all my friends had this perfectly straight blond highlighted hair.” When, aged 15, she asked her friend to come with her to a bashment party called Jamaican Club in Gloucester, her friend only came once, because, she told twigs, she didn’t feel comfortable as the only white person there.

“And I was like, ‘That’s how I feel every day at school!’” Twigs says, almost laughing with outrage. “I got angry. ‘That’s how I feel when I go to your brother’s house party and it’s all Cheltenham Ladies’ College girls. When I go round people’s houses and they’ve got swimming pools and ponies in the back yard!’”

There is something about twigs that will always feel other, even now. She’s not often been allowed to fit in. When she moved to London and enrolled in dance college, she missed the first two weeks because her mother was looking for somewhere for them to live. Before she arrived, the teacher told the whole of her year and the year above that they had better start working, because this brilliant dancer was about to join them – twigs – and was going to wipe the floor with them. “So I turn up on my first day, in my pink leotard with my hair in a bun, with my farmer’s accent, like, ‘Hi guys!’ and everyone’s like, ‘No, absolutely not.’ My shoes went missing, my leotards… I think I lasted a month.”

People thought I was odd-looking, until a white male validated my beauty. But if I sing well, you can’t question that

She went to Croydon College to do six (six!) A-levels – sociology, psychology, fine art, English literature, philosophy, French – but found it hard moving into a class of 30 kids when, at her previous school, there were only 12. Everything was confused and confusing: she remembers going into an exam, looking at a question and thinking, “We haven’t been taught this.” After college, she wanted to get into the music industry, but couldn’t work out how you did it. So she was a youth worker in Borough and Tower Bridge, a shot girl at Tiger Tiger. She continued with her dancing. Then, when she was 24, a photographer spotted her and put her on the cover of style magazine i-D. She got a manager who started teaming her up with producers – surprisingly, she learned songwriting for a time with Mike Chapman, veteran of the Sweet (she tells me he taught her how to structure a song) – and finally, she released the four-track EP1, in 2012. Every track was accompanied by a video, directed by her.

It’s been a while since twigs has been asked to look so far back, and she is different now, she says. “I was a young woman, stepping into my sexuality and owning it. I was sassy! Coming from the outside and being alternative. Not like a Nubian queen, not a powerful goddess – but something just as powerful, but fractured. Like in Japan, where they smash the pots but join them up again with gold.”

Now, though less sassy, she still feels good. “People thought I was quite odd-looking, until a white male validated my beauty,” she says. (She means Pattinson.) “That’s frustrating and I still don’t accept it. But if I sing really well, you can’t question that. If I dance well, you can’t question that. If I express myself honestly, or if I’m pole dancing or wushu-ing excellently, you can’t question that. I’ve never felt more beautiful because I’ve never been more skilled. Everything else is ephemeral.”

She called her album Magdalene because of the way Mary Magdalene has been written about, she says: as a prostitute, when she was a healer and a mystic who washed Christ’s feet in rare and expensive oil. “An incredible woman who was always in the shadow of a man,” twigs says with irony. “I can relate.”

She’s a mass of contractions, twigs: a homebody who sparkles in the limelight, a seeker of male approval who wants to own her sexuality, a willing apprentice who’s made for centre stage. And the next few years will be about her. She might be in a new relationship – “Don’t get me wrong, I’m completely open to love” – but she doesn’t want to compromise, to mould her life around someone else, man or child. “I’d like children in my late 30s,” she says, “because as a dancer, your body doesn’t come back.” She wants to enjoy her new strength. “It would be a shame if I didn’t question what it is to be in a relationship,” she says. “I think I need to do that, to grow. And to make sure when I meet someone wonderful, it can be on my own terms. I hesitate to talk to you about it, because I would love to have a piece written about me where my name is not attached to a man.”

But you were dating someone very famous, I say.

“But my work was so beautiful,” she says. “It was so much louder than my love life. It is so much louder.”

• The album Magdalene is out on 25 October.
