While 2019 has seen girl bands the Spice Girls and The Pussycat Dolls make comebacks minus one member each - Little Mix have insisted that would never be the case for them.

In fact the group have declared they 'couldn't go on' if one of them quit - and that they can only ever be a four-piece.

Speaking to MailOnline exclusively, the band - comprised of Leigh-Anne Pinnock, Jade Thirlwall, Jesy Nelson and Perrie Edwards - even declared that they'll never feud, unlike the likes of Girls Aloud.

'I can't see us ever feuding. Or [if they ever split] getting back together without one of us being involved,' Jade, 26, said. 'People know we’re friends. It's not fake with us, you can just tell.'

'If one of us didn’t want to come back with us, we couldn’t do it,' Leigh-Anne, 28, added. 'Even the Spice Girls - who came back without Victoria - they could do it. But we couldn’t do it.'

Last summer, Spice Girls Emma Bunton, Mel B, Mel C and Geri Horner sold out stadiums around the UK for their sensational Spiceworld reunion tour, but were missing fifth original member Victoria Beckham.

Then, last week, American band The Pussycat Dolls reformed, this time missing Melody Thornton.

Rumours have swirled that Melody was not interested in a comeback, given that Pussycat Dolls front-woman Nicole Scherzinger is the lead singer, somewhat overshadowing the other members.

'You don’t know what goes on. People think we argue but we don’t,' Perrie, 26, said of the situation. 'And you know what? If Melody didn’t want to be there because she wanted more parts or whatever, so be it, each to their own.

'And if the other girls wanted to get back together as it was right for them, get yourselves away gorgie huns.'

But Little Mix have always been on an equal footing to one another.

'We have always made sure of that,' Jesy, 28, added. 'Everyone’s equal in this group.'

'We are a four. Little Mix isn’t Little Mix unless there's four of us,' Perrie added.

Last week, the band released their first Christmas single, One I've Been Missing, which was penned by Leigh-Anne.

The songstress - along with Jade - are the main scribes of the group, with Jesy and Perrie happily leaving them to it.

'With [albums] DNA, Salute, Get Weird and Glory Days, we all wrote for those. But then when it came to LM5, Jesy and I just went "you two, you’re nailing this" to Leigh-Anne and Jade.'

'I've just got no patience!' Jesy declared. 'With writing songs, I am either in it or I’m not. And if I'm not, I find it draining. I just either feel it or I don't.

'Jade and Leigh-Anne can stick at a song and it can get better. If I think it's s**t, I just give up. I sometimes look at these two and see their enthusiasm for a certain song and just think "really?"'

Jade elaborated: 'You can have sessions where nothing comes from it. You've got to keep at it though. And then all of a sudden you can have a hit.'

Leigh-Anne added: 'It feels like therapy. It depends on the emotions you're going through at the time.'

'Yeah, if I’m going through something and I'm like, this could be a song, then I'm totally there, living for it,' Perrie went on. 'I'm like, "guys, this is a concept of a song". But I can't be like, "I'm going to write a song about this today," or else I won't be able to do it.'

One I've Been Missing has been written by Leigh-Anne, and she'd kept it under wraps for some time.

'She had this little gem stored away and didn’t tell us about it,' Jesy explained. 'She came out with it in the summertime and said she had a Christmas song to play us. We were like this is amazing.'

Perrie interjected: 'Actually, at first, we were like, "Leigh its summertime, it's hard to get into the vibe". Then we listened to it and we loved it.'

Jesy went on: 'It’s different. It's got a different message. It’s not all "Merry Christmas!"'

Writer Leigh-Anne summed up: 'We can relate to it. It's about us missing our friends, family, being away from home. Missing our boyfs. And as for releasing a Christmas song - it was about time.'
