'Britain's Got Talent' Judge Simon Cowell Vowed by Striptease on Stage

If you thought it was hard to please Simon Cowell... and that the man never really smiled... well, you just didn't know how!

It took a striptease to put a grin on his face!

According to The Sun, during auditions in Blackpool, Beatrix Von Bourbon, 27, a burlesque dancer, took to the stage to carry out a striptease. She was dressed in red vintage-style skirt with gold heels.

At the end of her act, when she removed her skirt to reveal her thong, Cowell was clearly seen grinning!

The Sun also reported that Cowell compared Beatrix's performance to famous burlesque queen Dita Von Teese.

"You are the British version of Dita Von Teese and I'm going to back you," Cowell said at the end of Beatrix's show.

Meanwhile the host for the show, David Walliams had quite a field day, with jokes about Beatrix and Cowell!
