Who Should Replace Simon On Idol?

Season nine has only just gotten underway, but with the news that it will be Simon's last, we just can't help wondering who will replace him as the feistiest judge on Idol?

Rumor has it that Idol bosses are seriously considering former Sony Music chief (and Mariah Carey's ex) Tommy Mottola. But Tommy's name also came up in discussions to become a judge on Cowell's show X-Factor!

Madonna's longtime business partner Guy Oseary has also been mentioned as a fill-in, as was Interscope boss Jimmy Iovine. We can appreciate that the folks at Fox want to fill Simon's seat with someone who's got as much (or more) industry experience, but with Randy and Kara's expertise, should they go for someone with the wow factor instead?

Conan O'Brien's currently out of a job and said to be in negotiations with Fox -- Could CoCo replace SiCo?

Perhaps another tight-shirt wearing reality tv sensation like The Situation is what Idol needs to re-energize?

Jessica Simpson's boobs are much bigger than Simon's moobs, but we think the blonde isn't quite as air-headed as she seems when it comes to music!

Kanye West is known for his very public put-downs, could "I'm a let you finish" be the new "If I'm being honest?"

And Martha Stewart may be a felon, but she thinks she can fill the Brit's shoes best, offering her "fair" and "impartial" opinion.

But what do YOU think?
