Little Mix’s debut single as a three piece after Jesy Nelson quit the band has leaked online sparking an investigation by the group’s management.
The song, called Heartbreak Anthem, is a David Guetta collaboration featuring electronic duo Galantis.
In the track, Perrie Edwards, Leigh-Anne Pinnock and Jade Thirlwall sing about moving on from a break-up over synths.
The music video is set to be filmed by the trio in the coming weeks.
A source told Daily Star Online: “Little Mix’s management are looking into how the song appeared online as a matter of urgency.
“Heartbreak Anthem is a sugar sweet pop collab with David Guetta and Galantis – it has a 2011 vibe.
“No artist wants their music to leak ahead of it being announced but with this being Little Mix’s first single without Jesy it’s even more frustrating.”
A rep for Little Mix has been contacted by Daily Star Online for comment.
Earlier this month Little Mix had to postpone their tour for a second time due to the ongoing coronavirus pandemic.
The trek, which was initially slated for 2020, will now take place in 2022.
The tour will be the first time Little Mix have hit the road without Jesy.
The Essex beauty made the tough decision to call time on her days in the band to focus on her mental health.
Speaking via social media, Jesy said: “To all my Mixers, the past nine years in Little Mix has been the most incredible time of my life.
“We have achieved things I never thought possible. From winning our first Brit Award to our sold out shows at the O2.
“The truth is recently being in the band has really taken a toll on my mental health. I find the constant pressure of being in a girl group and living up to expectations very hard.
“There comes a time in life when we need to reinvest in taking care of ourselves rather than focusing on making other people happy, and I feel like now is the time to begin that process.”
She added: “I need to spend some time with the people I love, doing things that make me happy.”
Meanwhile, Little Mix added via a statement: “We are still very much enjoying our Little Mix journey and the 3 of us are not ready for it to be over.
“We know that Jesy leaving the group is going to be really upsetting news for our fans.
“We love you guys so much and are so grateful for your loyalty and continued support of all of us. We’re looking forward to seeing so many of you on tour.”
