Jennifer Lopez Sparkles in Sequined Dress on 'American Idol' (PHOTOS)
The 42-year-old beauty hit it out of the park in the super-short, age-defying cocktail dress, which, if anything, showed off her killer legs.
What else did she wear?
To complete the look, J-Lo wore a pair of sick black heels and gold hoop earrings. (At this point, can't they just crown her the winner of American Idol season 11?)
Jennifer -- who confirmed she'll be touring this summer with Enrique Iglesias, as reported first by Celebuzz -- is set to perform on tonight's elimination episode -- presumably her new single Dance Again.
What did you think of J-Lo's latest ensemble, and who will go home tonight to watch her on Idol? Sound off, below!
