Simon Cowell has reportedly revealed that he never wears any underwear.

Britain's Got Talent judges David Walliams, Amanda Holden and Alesha Dixon let slip the 52-year-old star's love of going commando during a recent radio interview.

"Simon doesn't wear underwear," Walliams told Radio 1's Nick Grimshaw.

Holden then piped in to say the media mogul "goes commando, all the time" before Simon apparently nodded to confirm he prefers to go without.

The judges are believed to have found out about Cowell's little secret during the BGT auditions.

"I can't reveal how we discovered this," Holden said.

Maybe because he has such a busy life he doesn't have time to put them on or take them off. Perhaps he should get someone to do that for him," she later joked.
