Who will join "Idol" next?

There's a lot of rumors flying around right now when it comes to "American Idol" and possible judges... and they include Charlie Puth, Lionel Richie, Luke Bryan, and the return of Keith Urban.

I really liked Katy Perry's (who we already know is signed on) suggestions of Tim McGraw and Rihanna, but I think that they may be too expensive to sign. However, the others that are rumored to sit next to her who cost a pretty penny too! If I could pick 1 to definitely be a judge out of those 4 rumored, I'm going with Luke all the way!!! Imagine the smack talk between him and his buddy, "The Voice" coach Blake Shelton.
