Jennifer Lopez took to the stage for the ‘American Idol’ Top 2 Live Performance Show in Hollywood, California last night with Steven Tyler and Randy Jackson.

The judge was back to her best wearing Zuhair Murad Spring 2012 Couture.

She wore a one-sleeve beaded black top with a cut-out shoulder and v-shaped structured hem with black leather pants.

JLo opted for a simple bun, black nail polish, Jacqueline Nerguizian onyx stud earrings and Jimmy Choo ‘Liv’ black heels.
