David Walliams wants to throw Simon Cowell a stag party themed around drag queens, but he's not convinced the TV impresario would be too keen on the idea.
Walliams told The Sun that he hasn't yet received an invitation for Cowell's wedding to partner Lauren Silverman and suggested even the date is still under wraps.

The Britain's Got Talent judge said he would be more than happy to organise his telly colleague's stag night, but said Cowell would probably rather he didn't.
Walliams said: "I don’t think our tastes would align on a stag night. I would do something like a drag stag, where I say all guys have to go in drag, and I don’t think that is what Simon would actually like.

"I think that would be his worst nightmare. There are things that Simon would find entertaining on a stag, and that’s not one. If I get invited that would be a thrill though."
As for the ceremony itself, Walliams said he expects it to be a big, glamorous affair in keeping with Cowell's reputation as one of music and TV's wealthiest personalities.
The 50-year-old said: "I don’t think it would be in Simon’s style to do a small wedding, as his 50th was a big do and I think if I was Lauren I would want to have a big dress and glitzy, exciting party.
"I’d be surprised if they just ran away to Gretna Green with two other people."
Walliams, who is currently on screen with Cowell for the 15th series of Britain's Got Talent, said he doesn't think he's on any sort of blacklist for the wedding, despite his lack of an invite thus far.
He said: "I certainly haven’t received an invite and I think people have read that as I’m not invited, but I don’t think anyone is yet. I think only they know when and where it is going to be.
"I am really pleased for them. They have their beautiful son together and it feels like the time is right."
