X Factor star Diana Vickers left everyone disappointed when she revealed she once spent the night with Leonardo DiCaprio.
The singer spills all on the forthcoming episode of Celebrity Karaoke Club, but her fellow contestants couldn't believe their ears when Diana said she'd simply "watched the telly" with the Hollywood hunk.
Diana, 29, told Courtney Act, Baga Chipz and David Potts that she'd once hung out with the Titanic star, and they were dying to know more.
But Diana let everyone down when she confessed that absolutely nothing happened between them, despite her wishing that it would.
She said: "I have a lot of stories but I'm just going to say one. The best one - I've been on a night out with Leonardo DiCaprio. That's my best one."
RuPaul's Drag Race star Courtney was quick to ask if Leo made a move.
"No, no," Diana said.
"I was more like hanging out with his friends and then I got a message being like 'oh come back, Leo, he's having a vibe' and I thought it was going to be all Wolf Of Wall Street, like a massive thing. And I got back there and it was [just the two of us].
"It was very chilled and we just ended up watching telly!"
RuPaul's Drag Race UK's Baga couldn't resist asking if they'd "s***ged in a car" like Leo did with his co-star Kate Winslet in a famous scene from Titanic.
"I wish," Diana shouted.
Diana, who took part in X Factor in 2008, said about joining the new ITV2 singing show: "I didn't know everyone that was doing it and obviously that is part of the surprise. I love karaoke and it is one thing that I have really missed.
"After lockdown, and when things were starting to open up, my friends and I were like, 'shall we see if the karaoke bar is open?'
"I really didn't take myself too seriously and I am not too sure how good I sound! It was more about going up there, performing, getting everyone's attention and it is basically a night out.
"I think people shouldn't expect a serious X Factor competition or anything like that – it is literally being a fly on the wall on a great night out at a karaoke bar with a fab group of people. We all really went for it!"
* Celebrity Karaoke Club airs Wednesdays at 10pm on ITV2
