Kate Upton Bikini: Model Wears Swimsuit On Set Of 'The Other Woman' (PHOTOS, VIDEO)

Kate Upton slipped back into her staple uniform, a teeny bikini, while on the set of "The Other Woman" Wednesday.

Upton stunned in a white string bikini and sunglasses while filming in the Hamptons, N.Y. The supermodel showed off her ample curves walking along the sandy beach and splashing in the waves. She even got a smooch from co-star Nikolaj Coster-Waldau.

The is not the first time jaws have dropped over the 21-year-old recently. Last week, Upton bared major cleavage (and narrowly missed suffering a wardrobe malfunction) while bouncing around in an open gauzy top and lacy orange bra on set.

"The Other Woman," directed by Nick Cassavetes, is a comedy that centers on a woman (Cameron Diaz) who gets revenge on her cheating boyfriend (Coster-Waldau). After she finds out he is married and has another mistress on the side (Upton), she teams up with his wife (Leslie Mann) to get even. This is Upton's biggest film project to date, notes The Hollywood Reporter. She previously had small guest appearances in "The Three Stooges" and "Tower Heist."
