Kate Upton showed just how she landed the cover of Sports Illustrated twice in the past two years, wearing a revealing white bikini while on the set of upcoming film “The Other Woman.” Filming in in Long Island, N.Y.'s Hamptons, Upton accessorized the revealing swimsuit with dark sunglasses and ran around the beach and played in the ocean while the cameras rolled.

The supermodel is making her acting debut in the comedy, which is directed by Nick Cassavetes and also stars Cameron Diaz, Taylor Kinney, Nicki Minaj and "Knocked Up" actress Leslie Mann.

At one point during filming, Upton had to readjust her top to avoid a wardrobe malfunction, and it is not the first time she almost showed off too much skin.

Just last week, while filming a scene alongside Mann, Upton nearly suffered a wardrobe malfunction while wearing a loose white tank top that showed off a yellow bra and her famous cleavage. Her bra and cleavage were even more visible as she and Mann bounced up and down on the set in a seemingly cheerful mood.

The blonde bombshell, who turned 21 years old on Monday, shot to fame last year after doing the "Cat Daddy" dance move in a video for famed photographer Terry Richardson. Wearing just a tiny bikini, she danced to music by the Rej3ctz. The video quickly went viral. 

Upton has since had quite a busy career, landing on the cover of Sports Illustrated magazine two times, being featured on Maxims’s Hot 100 list and being labeled the "sexiest supermodel on Earth" by Vogue.

She is now rumored to be dating "Dancing with the Stars" pro Maksim Chmerkovskiym and was previously linked to Justin Verlander, a MLB baseball pitcher for the Detroit Tigers.
