American Idol First Look: Celebrity Judges Galore!

Yes, Ellen DeGeneres is coming on board American Idol as a season nine judge.

But not until February 9, when the world's most popular television show moves to Hollywood.

Until then, Idol will feature its three main judges - Simon Cowell, Randy Jackson and Kara DioGuardi - along with a special celebrity judge each week. These guest panelists will include:

Neil Patrick Harris, Avril Lavigne, Mary J. Blige, Shania Twain, Katy Perry, Victoria Beckham and Joe Jonas.

But don't just take our word for it. Check out shots of these actors and singers in their unique roles below. (And let us know if you can figure out what Victoria Beckham knows about singing.)
