Ryan Seacrest Returning as 'American Idol' Host in New Deal

Host Ryan Seacrest has signed a new deal to continue on the show, which he's hosted for the past 17 seasons (the first 15 of them on Fox). He joins judges Katy Perry, Lionel Richie and Luke Bryan, who closed their deals in August. Bobby Bones is also set to return as Idol's in-house mentor.
