JESSIE J said that she is a "diva, total bitch, and a nightmare" in a cryptic post following her split from Channing Tatum.
Earlier today, the 31-year-old star reassured fans that she is "happy" after news of the break-up went public.
But now she has returned to social media to reflect on how much she has changed over the last eight years, sharing a throwback snap of her 2011 tour poster.
Jessie wrote: "This week in 2011 maybe even 2010?! Anyone know?! Lol!! I was finishing my first ever UK tour. MUAD!
"I remember the Scala gig like it was yesterday. It’s where I recorded ‘Big White Room’ for the Who You Are album.
"AND... I was doing three shows back to back. Don’t do that now.
"That’s because I’ve changed. I’m a diva. A total bitch. A nightmare."
The cryptic words came just hours after the British singer shared a video of herself in a sexy leotard.
The brunette beauty looked sensational in the sizzling post, which she seemingly used to reassure her fans that she was "happy" in the simple caption.
She and 39-year-old Channing are said to have ended their romance around a month ago.
A source then spilled to RadarOnline that the Hollywood hunk has already signed up to an exclusive dating app.
They shared: "Channing's new profile popped up for LA users of the app last week, it's full of sexy photos and he's been very active on it.
"Nobody can quite believe he's moving on so quickly.
"It doesn't look like he's nursing a broken heart or thinking about patching things up with his ex, and it's likely Jessie's friends have already seen the profile as the app is so popular."

Channing shocked fans when he moved on with Jessie just months after breaking up with his wife of nine years Jenna Dewan, who he shares six-year-old daughter Everly with.
The two were first linked in October of last year, although they were said to have been dating for a few months already at that time.
Channing and Jenna split in April 2018, and the brunette beauty previously admitted to feeling "blindsided" by how quickly her ex-husband had moved on.
Yesterday, a source told Us Weekly that it was all over between Channing and Jessie, sharing: "Channing and Jessie broke up about a month ago.
"They are still really close and still good friends."
