David Walliams performed a "lap dance" for Simon Cowell while filming for 'Britain's Got Talent'.
The 'Little Britain' comedian - who is joined on the panel of the ITV1 show by the music mogul, as well as Alesha Dixon and Amanda Holden - admitted he has been doing a lot of "flirting" with his fellow judge, but he thinks Simon secretly "likes the attention".
He said: "I have been flirting with Simon a lot. I even did a lap dance for him. I think he likes the attention."
While David had previously turned down Simon's requests to join the panel of 'Britain's Got Talent', he admitted he has enjoyed the experience so much that he even joined one particularly camp act on stage for a rendition of 'It's Raining Men'.
He added in an interview with the Daily Telegraph newspaper: "You don't want to be unpleasant, but you still need to give people pointers. You have to have a dream that suits you.
"We had one group called Show Bears. They were five guys in sparkly sailor suits, who sang their own version of 'It's Raining Men,' I ended up on stage doing dance moves with them. It was only the second day of auditions, and I thought, 'I've found my spiritual home!'"
David has previously joked that his Dutch supermodel wife Lara Stone is jealous of his 'bromance' with Simon, as he has started forcing her to wear a mask of the music mogul's face in the bedroom.
He said: "Lara is jealous because every time I come back from work I say, 'Guess what Simon did today?' so she actually doesn't really like it. Also, in our wedding photograph I've taken her head away and replaced it with Simon's.
"Sometimes when we get into bed at night I say, 'Is it OK if I call you Simon?' For the first few times she let me, but then she was wearing the mask..."
