Here’s everything you need to know about the Demi Lovato UK tour - plus new album ‘Tell Me You Love Me’.

UPDATE: Demi Lovato resumes tour, reschedules London and Birmingham concerts

Demi Lovato gave a killer performance at her Glasgow concert on June 13 after being forced to cancel two huge UK concerts due to illness.

The 'Cool For The Summer' singer is suffering from swollen vocal chords and was confined to her hotel room - meaning her London AND Birmingham had to be rescheduled.

She tweeted, “I’m literally gutted that I have to postpone this next show in Birmingham.

“I’ve never had to miss shows due to my vocal chords or being sick in my LIFE.”

After cancelling her London concert (The O2 Arena), Lovato posted a heartfelt message to her Instagram followers explaining how difficult the decision to cancel was for her.

It read, “If I go on tonight and injure my vocal chords, I could potentially have to cancel the rest of my tour. I’m so so sorry to disappoint any of my fans in London that have travelled hours to be here by plane or car, and to all of the fans that got these tickets for their birthday, holiday or any other special occasion."

Check out the rescheduled dates in the list below.

Demi Lovato has never done a UK tour.

The only time the singer has ever performed in the UK was a one-off concert in London as part of the ‘Neon Lights Tour’ way back in 2014 - and fans were getting impatient...

Prior to Demi Lovato's UK concert date announcement, Lovato teased some 'big news' coming soon on her Instagram page.

The star posted a racy image to the social media site alongside the cryptic message, prompting speculation that we'd finally find out when Demi Lovato is coming to the UK.

Lovato revealed her plans to make her concerts an "up close and personal" experience.

She told Billboard, "I'm going to utilise the arenas and really make sure that from every seat, you get to see my performance up close and personal, as much as we possibly can."

Lovato revealed the name of the tour to the audience of 'The Ellen Degeneres Show'.

She said, “It’s actually called the 'Tell Me You Love Me Tour'. I just got so excited to say it out loud because this is the first time I’m saying it out loud.”

Demi Lovato will be offering free therapy sessions on her UK tour in 2018.

The singer - who herself has suffered from mental health issues - is partnering with CAST to offer fans a safe place to discuss their problems.

This is not the first time the star has advocated mental health on tour. Lovato invited guest speakers to discuss their experiences with mental health on her 2016 tour including Joe and Nick Jonas.

She told Good Morning America, "I want to do this because one, it was such an incredible experience the last time we did this on tour.

"It's a part of my whole life, about giving back and I think it's really important that I continue to do this while I'm on tour."

Demi Lovato support act for 2018 tour

The singer surprised fans when she announced she will be touring in the US with 'I'm the One' hitmaker DJ Khaled. The singer teased a "major announcement" before dropping the news on Twitter.

But it's not the first time the pair have teamed up.

Lovato wowed the audience at iHeartRadio Music Festival when she made a surprise appearance alongside the DJ.

However, it seems DJ Khaled will not be joining Lovato for her UK and Europe concerts.

Demi Lovato announced that DJ and producer Jax Jones - with whom she collaborated on the track 'Instruction' - will be joining her on her UK tour dates in London, Birmingham, Glasgow, Newcastle and Manchester.

UPDATE: And now another support act for Lovato's UK and Europe dates has been confirmed.

Australian singer Joy was announced as a late additional support act for the UK concerts alongside Jax Jones and will follow the star on her Europe dates.

She told Perth Now's Confidential section, “I’m so-so honoured to currently be on tour with Demi Lovato.”

New Demi Lovato album: everything you need to know

Despite announcing she would be taking a rest from the music industry in 2017, Demi Lovato soldiered on with a series of live performance and collaborations.

During the first half of the year, the singer teamed up with Cheat Codes on their hit track ‘No Promises’ as well as Jax Jones for ‘Instruction’.

Lovato later released her own record ‘Tell Me You Love Me’ in September 2017 to critical acclaim. It was her highest-charting album in the UK at number five and hit number three in the US.

#TellMeYouLoveMe is here. Proud of this record. I really hope you love it as much as I do. https://t.co/Be7ZjlabHz pic.twitter.com/1gmtL7QJCz — Demi Lovato (@ddlovato) September 29, 2017

The star revealed that her biggest inspirations for the new album - which has a clear soul/R&B style - were Aretha Franklin, Christina Aguilera and Kehlani.

The first single to be released from the album was ‘Sorry Not Sorry’. According to Lovato herself, the top 10 hit is a stab at all the haters that gave her a hard time and to tell the world that she’s OK now following her stint in rehab.

In an interview with Noisey, Lovato revealed that she wanted the fun track to be the lead single from the album, but her management thought the title track was the way to go. That is, until she got the opinion of a certain hip-hop legend...

She revealed, “I played Jay-Z both songs. And he said 'Sorry Not Sorry' should be the lead single because it was lighthearted. He was like, 'A lot of people see you do the emotional thing all the time, but they don't see you have fun!' And I was like, 'That's such a good point.' And his opinion kind of persuaded other people, too."

While not the album’s lead single in the end, ‘Tell Me You Love Me’ was later released to further promote the record. Before the official video dropped, the star released her Vevo X live session recording on her YouTube channel.

Lovato released two further singles ahead of the album: ‘Don’t Do It For Me Anymore’ and ‘Sexy Dirty Love’.

After the album dropped, a lyric video for 'Hitchhiker' was published on her YouTube page to coincide with the release of her new documentary 'Simply Complicated'.

Demi Lovato and DJ Khaled have released a video for 'I Believe' from the soundtrack to Disney's new film 'A Wrinkle In Time'.

The promo shows the pair singing the track against a stunning natural backdrop intercut with clips from the film, which stars Oprah Winfrey, Reese Witherspoon, Mindy Kaling, Storm Reid, Zach Galifianakis and Chris Pine.

Demi Lovato also released a collaboration with pop icon Christina Aguilera.

In an interview with Billboard, Lovato revealed she would be working with someone she really looks up to, and in a previous interview said Aguilera is an idol or hers and that she inspired Lovato's latest album. Aguilera's make-up artist also posted a pic of Lovato on Instagram saying, "something dope coming soon."

Before the collab dropped, Lovato teased, “I did a collaboration with one of my biggest idols. I can’t give away who it is yet, but you’ll find out soon. I can’t wait for the world to hear it. It’s an incredible song.”

Demi Lovato released her new documentary ‘Simply Complicated’ back in October.

A full trailer for the documentary came later, detailing her struggles with tour stress, anxiety, drugs and an incident in which she punched a backing dancer in the face.

The full documentary was released for free on her YouTube channel. In it, the star reveals details of her sexuality, depression and drug addiction that started in her teenage years.

She said, "My first time doing coke, I was 17 working on Disney Channel, and I was with a couple of friends and they introduced me to it. I was scared because my mom always told me that your heart could just burst if you do it.

"But I did it anyways and I loved it. I felt out of control with the coke the first time that I did it.”
