J.Lo And Casper Smart Are Picture Perfect In Las Vegas

Jennifer Lopez was a major fashion hit on Saturday as she flaunted her fit figure in an LBD for an event in Las Vegas.

The 43-year-old superstar was joined by her boyfriend Casper Smart as the pair joined a number of celebrities in celebrating the opening of Hakkasan Las Vegas Restaurant and Nightclub at the MGM Grand Hotel and Casino.

The couple shared a few laughs as they pose for photos together on the blue carpet.

Paris Hilton, Vanessa Hudgens, Calvin Harris and Pharrell were also spotted at the event.

Next up for J.Lo: a new single called “Live It Up,” set for a May 8 release, and the June 3rd premiere of The Fosters, an ABC Family TV series produced by the singer.
