'Britain's Got Talent': David Walliams Teases Simon Cowell About Having 'Work' Done On His Face

Comedian David Walliams could not resist ribbing show boss Simon Cowell at the latest 'Britain's Got Talent' audition - teasing that he looked as though he has had some "work done".

The 'Little Britain' funnyman, 41, poked fun at the TV mogul's age, career and even his new racehorse as they watched potential acts for the forthcoming series.

They attended an audition at the London Palladium alongside fellow judges Amanda Holden and Alesha Dixon.

David turned on chief judge Simon after the music mogul asked one contestant their age.

He asked Simon: "How old are you? You've had a lot of work done."

And he took a swipe at Simon's TV career after he had suggested one act was not very "likeable".

But Simon hit back: "It doesn't matter whether people like me or not, I'm a good judge."
