Jennifer Lopez was livin' it up in Las Vegas this weekend - and she was definitely looking like a Showgirl in this teensy leg-revealing LBD.
The pop star arrived at the Hakkasan Las Vegas at MGM Grand for a GQ Magazine-hosted bash in her microscopic halter neck number with her hair up in a playful ponytail.
She finished the look with black pumps (we think strappy sandals would have looked better), and matched her lipstick to boyfriend Casper Smart's suit jacket. Cute.
What d'ya think of J-Lo's Las Vegas look?
