Westlife singer, Nicky Byrne has told The Sun, that in America, X factor judge Simon Cowell is more famous than Brad Pitt.

Nicky commented: “Simon is bigger than Brad Pitt in America. Ever since he started American Idol he’s become a megastar.

“We met up with him in the States a couple of years ago but we couldn’t get near him because he was so busy signing autographs.

“We take the mickey out of him. In his office he has a mirror that says, ‘Yes, Simon, you look terrific’. ”

But Byrne also claims that the new celebrity status has not changed Cowell stating: “He wasn’t famous when we first met him but he hasn’t changed. How you see him behave on The X Factor is how he has always been.”
