Britain's Got Talent latest: Simon Cowell's back, David Walliams is too rude

Simon Cowell's polished his teeth (and adjusted his trousers to hoisty) while Amanda Holden's put her claws away for five minutes, it must be the return of Britain's Got Talent. And while Alesha Dixon is wowing the crowds with her Cheryl Cole-alike wardrobe, fellow newbie David Walliams has come under fire for his risque wit.

According to show insiders, bosses have become worried about David's smutty remarks during the auditions. Most of his comments will apparently have to be edited out of the show because they're too rude to air on ITV1 before the 9pm watershed.

Surely they've seen him in that little known comedy, Little Britain?

Boss-man Simon is said to be happy with the line-up though. The source also told The Sun that "he loves the banter". We're not sure Herr Cowell would phrase it like that though.

He's also been telling whoever will listen that he expects ratings of 20m this year. No pressure...
