Rihanna to Guest Judge on “The X-Factor”

After her performance last year on The X Factor, one of our favorite Vixens returns to the show–this time as a judge.

Rihanna will serve as a guest to L.A. Reid on the U.K. based talent show that migrated to the states this season. Guests are asked to help the show’s regular judges pick contestants to mentor.

The X Factor premiers on Sept. 21, 2011. Catch the show on Wednesdays at 8 p.m. on Fox.
