On Sunday, the swimsuit model attended the stylish event wearing a custom black Versace dress with a v-neck, padded shoulders and draped detailing pulled together by a studded belt.
The 21-year-old Vogue cover girl was at the show to present an award with her "The Other Woman" co-stars Leslie Mann, Nicki Minaj and Cameron Diaz.
While all of the ladies looked gorgeous (especially Nicki in a stripped down LBD), Kate stood out thanks to her vampy makeup: a dark berry lip and smoky eyes.
One big change to the Sports Illustrated model's style? The lack of cleavage! Kate hid her girls as best she could in the tight frock, and it may be because she recently admitted to The Sun that she wishes she had a smaller chest.
"I wish I had smaller boobs every day of my life as I would love to wear spaghetti tops braless or go for the smallest bikini designs," Kate said. "Every single day I'm like, 'Oh man it would be so much easier,' especially if people didn't constantly bring them up."
