JLo's above-the-shoulder tresses were styled in curls, and she glammed up with a full face of make-up.

The On The Floor songbird was joined by Ray Liotta and Drea de Matteo.

They all appeared tense while watching a man rolled out on a stretcher as they filmed the scene.

The singer hopped on stage at the MGM Grand Garden Arena in a multi-strapped white bodysuit which put her stunning curves on display.

With two sheer straps crossing over her bust, Jennifer also showed off plenty of cleavage in the skimpy ensemble.

Covering her toned pins was a pair of flesh-coloured fishnet tights and she completed the look with gold lace-up heels.
