'American Idol' finale: Cat Deeley thinks Elton John could replace Simon Cowell

Cat Deeley, the host of "So You Think You Can Dance," came out to wish Simon Cowell farewell at the Season 9 finale of "American Idol."

She thinks Sir Elton John might make a good replacement for Simon. "I think he would, possibly. You need someone who is going to say what they mean, not sugar coat everything and have some kind of  experience in the industry and he would be witty, funny and clever. And more importantly, entertaining."
