Kate Upton: Bikini scene on beach uncomfortable

Model Kate Upton said she was "a little uncomfortable" filming her bikini scene in her first film, The Other Woman, because the film crew was staring at her. "It was funny because when we were filming that scene, whenever you go to a beach, everyone's wearing bikinis, so it's just pretty normal. It's part of life," the Sports Illustrated model said. "But when you're filming a bikini scene, nobody's wearing a bikini, it's only you and 60 crewmembers. And these two saw that I was feeling a little uncomfortable, because anyone's uncomfortable when that many people are staring at you." She said costars Cameron Diaz and Leslie Mann helped her through her first movie role, though. "This was my first movie role and these two supported me every step of the way," Upton said. "They made me feel so safe from day one. They encouraged me to mess up and try new things and they were amazing examples." "She's fearless," Diaz said. "I mean she really went for it." Upton said she didn't feel she was in the best shape for the sexy scene. "Of course, I always try to live a healthy lifestyle, but that was my birthday week," she said. "So that was the least healthy I've ever been. I just turned 21...Cameron, Leslie and I were just living it up that week."
