David Walliams jokes about why Simon Cowell is so happy: 'He's having regular sex'


David Walliams has poked fun at Simon Cowell, putting his recent high spirits down to his relationship with Lauren Silverman.

Arriving at the Britain's Got Talent launch in London, David took advantage of his co-judge's absence to dress up as Simon - with his trademark sunglasses, black trousers pulled up high and a white shirt with a bit of chest exposed.

He also made jokes at the TV mogul's expense.

"Simon's been in a good mood this year. I think he's having regular sex," the London-born comedian and children's author quipped.

David then poked fun at The X Factor chief and former judge Louis Walsh when asked what he would do if he were Cowell for a day.

"I'd get up at about four in the afternoon and say, 'Louis, it's time to get up!" he joked.

David said the foreign acts who participate in Britain's Got Talent "set the bar higher" for the ITV talent show.

The 44-year-old judge defended the non-British acts who have, to date, signed up for Britain's Got Talent (BGT).

"It's sort of become 'World's Got Talent', this show, and that puts us in a very special place," he said.

"I hate to think we wouldn't have people from around the world because they set the bar higher.

"It would be quite tough when you've got one person from Spain and one person from England and you say, 'You can't enter'. Or, 'You are British, but you grew up here or you moved from there'.

"I like that it's open for everybody," he stated.

Show boss Simon, 56, was absent from the launch due to filming commitments for America's Got Talent.

Meanwhile, BGT's Alesha Dixon, 37, ruled herself out of The X Factor judging chair recently vacated by Cheryl Fernandez-Versini.

She said she "respects" the singing talent series, but enjoys working on BGT because it is a less serious show.

On Saturday, viewers will see Simon, David, Alesha and Amanda Holden cast an eye over acts including singers, dancers and performing animals.

Once again, TV duo Ant and Dec are on hand to encourage the auditioning acts battling for the opportunity to appear at the Royal Variety Performance.

David said Simon's approval still means a great deal to the contenders.

He joked that the rest of the panel, himself included, are "window dressing".

"When he says no and we all say yes, the contestants are still really disappointed that they've got through," David said.

"They know he's the one who can make them a lot of money. We're pretty much window dressing."

Amanda, 45, has been in the hot seat ever since the very first series back in 2007.

When asked to account for her durability, she said: "I enjoy it. I do feel lucky. I get on really well with Simon."

Talking about the acts tasked with winning over the panel and public, David sympathised with the comedians.

"It's doubly tough for the comics on this show," he said.

"The audience has been there a long time and they're generally not as patient as they might be in a comedy club and it's quite tough to come on and have to talk about it before you do your act as well, if you're a comic."

He added: "It's rare that they do well. When they do, it's great."

Britain's Got Talent is broadcast on Saturday at 7pm on ITV.
