It's a battle of the blondes! Kate Upton, Cameron Diaz, and Leslie Mann hit the red carpet in Westwood, Calif. on Monday, April 21 to promote their new movie, The Other Woman

The three women star in the comedy as unlikely friends who get to know one another because they are all sleeping with the same man. The blonde bombshells all turned heads at the film's premiere, trying out different styles on the California evening.

Upton, 21, earned one of her first feature film credits for The Other Woman, going formal for the movie's premiere. The bodacious Sports Illustrated model wore a silver strapless Dolce & Gabbana minidress, adorned with sparkles and flower appliques. She accessorized with sparkling silver jewelry including Chanel drop earrings and silver pointy-toe Giuseppe Zanotti pumps. While her famous cleavage was covered up, the short length of the dress showed off her legs. Upton played up her eyes with black liner and major lashes, and wore her blonde hair pulled back into a knot at the center of her head, a look created by celeb hairstylist Peter Butler using Leonor Greyl products.

Diaz, 41, stunned in a plunging black Stella McCartney dress, which showed off her décolletage. Wearing a low-maintenance hairstyle and a bright pink lip, she accessorized the strapless silk frock with ear bling courtesy of Ana Khouri. The funny lady completed the number with a bold pair of Manolo Blahnik ankle-wrap heels.

Mann, 42, stole the show in a two-piece ensemble from Monique Lhuillier's Spring/Summer 2014 collection and a pair of Oscar Tiye sandals. The wife to director Judd Apatow showed off her figure in the bright pink strapless crop top and a voluminous orange floor-length skirt with a side slit. She wore her blonde locks swept to the side and finished with a punchy lip color.
