Jennifer Lopez performed "I Luh Ya Papi" on American Idol last night, and the 44-year-old singer/actress pretty much stole the show in her sparkly denim daisy dukes. Or is that a romper? We can't even tell but we're blown away by her amazing bod!

Lopez was joined by past show contestants Pia Toscano, Jessica Sanchez and Allison Iraheta, and later on rapper French Montana joined the ladies onstage.

J. Lo posted a handful of photos to her Instagram and wrote "thank you" to her adoring fans, adding that she "had so much fun performing."
