Yesterday the "Battleship" Los Angeles premiere was a star-studded event. Singer Rihanna, who stars in the film, wore a low-cut tantilizing white dress that showed off quite a bit of skin.

Not to be outdone, her model co-star, Brooklyn Decker, also revealed a little bit of leg on the blue carpet in a strapless gauzy gown.

Malin Akerman opted for an unusual black dress, while a very pregnant Molly Sims showed off her round belly in a geometric-patterned ensemble.

Actors Alexander Skarsgard, Liam Neeson, and Taylor Kitsch also attended the premiere.

The film, based on Milton Bradley's board game, centers on an international naval fleet fighting an army of invading aliens. It hits theaters May 18.
