Jennifer Lopez Dazzles in Low Cut Gown at Billboard Awards

Jennifer Lopez walks the blue carpet at the Billboard awards with Casper Smart.

Jennifer Lopez, who is riding high on the release of her hot new video for “Live It Up,” hit the Billboard blue carpet in a stunning, low-cut Zuhair Murad gown that showed off her toned mid-section and ample cleavage.

Lopez, 43, was accompanied by her 24-year-old boyfriend Casper Smart, who choreographed the video.

The awards show was held at the Las Vegas MGM Grand Garden Arena today (May 19). Lopez is on tap to perform her song during the evening.

She topped off her outfit Christian Louboutin shoes and bag, and Le Vian jewelry.

Lopez is rumored to be returning next season to “American Idol.” The show wrapped its 12th season last week by naming R&B and soul singer Candice Glover the winner. She edged out country singer Kree Harrison.
