Jennifer Lopez brought her insanely fit body (and very little clothing) to the Megaton concert stage at Madison Square Garden in New York City on Oct. 28. The singer and Shades of Blue actress joined reggaeton star Wisin for a supersexy performance of their song “Adrenalina.” (Sadly, Ricky Martin, also featured in the song, wasn’t there – he was busy performing with Taylor Swift in Miami.)

Jennifer looked gorgeous, as usual, in a low-cut belted metallic bodysuit, fishnet tights, and knee-high suede boots, but her edgy sideswept ’80s-inspired updo definitely stole the show – OK, fine, her legs and cleavage probably did!
