Vegas was the place to be last night. The highly anticipated fight between Floyd Mayweather Jr. and Conor McGregor took place at the T-Mobile Arena, and the stars came out by the dozens to watch the two legendary fighters duke it out.

The front rows of the arena were filled with A-listers like J.Lo and A-Rod, Charlize Theron, Karlie Kloss, Leonardo DiCaprio, and Orlando Bloom, just to name a few. Demi Lovato, for her part, was stunning in white as she sang the National Anthem. All were treated to a great event, too, with Mayweather coming out on top with a 10th round knockout.

These two certainly know how to do Vegas, as they jetted off to Sin City with none other than New England Patriots owner Robert Kraft.

Actress Charlize Theron also dressed to impress for the big event. The 42-year-old Atomic Blonde star sported a black coat and several layered necklaces as she sat in the crowd.
