Jennifer Lopez: Hollywood Week on American Idol!

Jennifer Lopez steps out in a Versace mini dress with sexy cut-outs as she heads to judge American Idol‘s Hollywood Week on Tuesday (December 7) in Los Angeles.

The 41-year-old entertainer joins Steven Tyler and Randy Jackson on the judging panel for the show’s tenth season.

Idol is making changes to the show’s format this year – contestants will make music videos and the top 24 round is gone – successful singers in the Hollywood round will go directly to the top 12!
