In the seemingly flawless photo, Lopez rocks navy body-hugging shorts, which perfectly show off her very voluptuous booty. She styled the tiny bottoms with a white blouse, sky-high black stilettos and a bold red lip.

Earlier this week, the Shades of Blue actress gave her fans a sneak peek listen of the track -- which will officially be released Thursday night on iTunes -- on her Instagram, and we're already obsessing over the catchy chorus.

The pop star will perform the full-length song for the first-time ever on the American Idol stage on Thursday, as part of the two-night series finale that kicks off Wednesday at 8/7c on FOX.

J.Lo isn't the only one performing on the highly anticipated finale, however. Idol alums Kelly Clarkson and Carrie Underwood are also set to take the stage!
