"American Idol" judge Simon Cowell and the man who discovered Susan Boyle on the British show "Britain's Got Talent" may quit the latter show in an effort to concentrate on his own show "The X Factor" which he is bringing to the U.S. later this year.

Grumpy Cowell, who is also leaving "American Idol" this year is getting his fill of all the shows he judges.

After watching a "silly little act" for "Britain's Got Talent" Cowell said, "What the hell? I'm not going to be back next year. I'm not kidding. I can't do this anymore."

He also said, "I like the show, but it takes a hell of a lot of time and there are moments, I am not going to lie, where you are sitting there looking at these horrific acts and you actually think I genuinely can't do this any more. But then you watch it back and you think it was all fun.

Can I see the show working without me? The answer is yes."

So who would replace Cowell on the show if he leaves.

His answer, "I don't know to be honest with you. You have really got to know what you are talking about and you have really got to be able to spot a star."
