Simon Cowell has responded to Amanda Holden's recent admission that he doesn't wear underwear.

The intriguing claim was made recently by the Britain's Got Talent judge as the TV show begins to promote its news series.

She said at the time: "During the auditions we discovered that Simon doesn't wear pants. I can't reveal how we discovered this."

Speaking at the launch of the new Britain's Got Talent yesterday (April 11), Cowell retorted by joking about Holden and promiscuity. He said:

"I think you're the one who's known for not wearing knickers."
