The Other Woman doesn't hit theaters until Friday but Kate Upton's boobalicious white bikini scene on the beach is already on its way to reaching iconic status.

But get this—Upton thinks she could have looked better

"Of course, I always try to live a healthy lifestyle, but that was my birthday week," the Sports Illustrated model told me at last night's Other Woman premiere. "So that was the least healthy I've ever been. I just turned 21."

Her costars Cameron Diaz and Leslie Mann helped her celebrate the milestone. "Cameron, Leslie and I were just living it up that week," Upton said.

If that's what living it up for a week gets ya, Kate, you're doing better than fine!

The flick stars Mann as a woman who seeks revenge on her cheating husband (Game of Thrones' Nikolaj Coster-Waldau) with two of his mistresses (Diaz and Upton). Rounding out the cast are Taylor Kinney as Mann's brother and Nicki Minaj as Diaz's assistant.

Diaz and Mann helped ease Upton's nerves when she first arrived on set. "I was definitely nervous and I didn't know what to expect," she said. "I'm the kind of person who really likes to know what's coming next, but Leslie and Cameron were just warm right away and supported me every step of the way and made me so comfortable. I felt like I was in a safe place."

"In comedy, it's important to feel like you're in a safe place so you could push your character and be silly and do ridiculous things," Upton continued.

Diaz was also feeling all the good vibrations. "The girls are so amazing," she said. "They're so funny and so talented and so fearless. I'm really lucky to have them as my partners."
