Is this the new cat dance? Kate Upton joined seasoned comic actress Leslie Mann shooting comedy The Other Woman at the Hamptons in New York's Long Island on Thursday, June 6 -- and the 20-year-old Sport Illustrated Swimsuit model narrowly avoided a major wardrobe malfunction as the twosome boogied on a trampoline.

Although the buxom blonde wore multiple layers (yellow bra, lacy white top and a salmon-toned hoodie sweatshirt), her world-famous cleavage was barely contained as she and Mann, 41, shimmied and bounced for the scene, in which their characters appear to be inebriated. The romantic comedy also stars Cameron Diaz and Taylor Kinney.

"You sit there and you're like 'Is something wrong with me?" she told Vogue. "The things that they're rejecting are things that I can't change. I can't change my bra size. They're natural! I can work out and I can stay healthy and motivated, but I can't change some things."
