Inside the event, held at Brooklyn's Kings Theater, Williams posed for photos with Wonder Woman star Lynda Carter and singer Nick Jonas.
She also presented model Gigi Hadid with the Supernova Award.
"Gigi, you are one of the few people on this planet I would leave my baby for -- for one night -- but for you, it shows how much you mean to me,” Williams said on stage, according to E! News. “And I want you to imagine the affect you have on the world."
"She understands that in order to be the best, you have to think like you are the best, work the hardest, and make sacrifices,” Williams continued. “Gigi pushes boundaries. In fact, she makes new boundaries. And she's authentically herself."
