This is what we'd like to call synergy. Ryan Seacrest is the host of American Idol, which is now in its final season. But he's also the executive producer of Keeping Up With the Kardashians, so it probably wasn't hard for him to get Kim Kardashian and her husband, Kanye West, onto American Idol for a celebrity pull. Smart. Here, Kanye auditions for Keith Urban, Harry Connick Jr. and Jennifer Lopez, as he raps a verse from "Gold Digger."
