Jennifer Lopez Gets "On the Floor" on American Idol

American Idol didn't look far for a big-name musical guest last night. Jennifer Lopez just had to get out from behind the judges' table and get "On the Floor"!

Rapper Pitbull joined her, working through the audience before J. Lo took the stagae wearing a silvery two-piece outfit with lots of fringe and lots of sparkle.

After she shattered a couple of dance cages with her shoes, she worked the stage with her dancers. Watch her performance below and see how she did:

Following Jennifer's performance, Jacob Lusk was eliminated, leaving only Scotty, James, Haley and Lauren to vie for the 10th American Idol crown.
