Jennifer Lopez Continues Her Daring Skin-Baring Tradition With Casper Smart

Jennifer Lopez and Casper Smart at the 2013 Billboard Music Awards.

Jennifer Lopez wore a sexy gold Zuhair Murad gown with a plunging v-neck to hit tonight's blue carpet at the Billboard Music Awards in Las Vegas. In typical J Lo fashion, she wasn't afraid to show off some skin thanks to the daring neckline. Her beau Casper Smart accompanied her for the big night out. Jennifer will not only be in the audience but she also has a performance during tonight's show as well. She got in a bit of practice ahead of her performance tonight since she made her return to American Idol on its season finale on Thursday. Jennifer sang her new song "Live It Up" alongside Pitbull, and she is set to perform the same track tonight.
