'X Factor's' Simon Cowell: 'Justin Bieber's a good example of someone who has the 'X factor''
"It's very difficult to write down in words what makes somebody special. But when they walk in the room it could be presence, it could be their voice, it could be the effect they have on other people," says Cowell. "I guess Justin Bieber's a good example of someone who has the 'X factor.' But you recognize it when you meet him or you see him perform, and like I said, he has that incredible effect on his fans - and that means he has it. And I've seen other people his age look almost identical to him who haven't got it. It comes from within I think."
He also says that out of all the artists he's discovered over the years, he's most proud of Leona Lewis. And that his favorite pop stars today are Adele, Rihanna and Jessie J," a British girl he says "is about to break in America."
"The X Factor" is set to debut September 2011. Will you be tuning in?
