She has been making some daring choices on the red carpet lately. And Sunday night was no different at the Billboard Music Awards in Las Vegas.

Jennifer Lopez wore a very 𝓈ℯ𝓍y gown that not only hugged her curves, but also showed off her stomach and underboob. The 45-year-old singer was in an open mood as well as she told Giuliana Rancic, 40, that she will miss American Idol, which was canceled earlier this week.

Also with her was on-again beau Casper Smart who arrived separately but sat next to the AKA singer during the show.
