'The Host' Hollywood Premiere [Slideshow]

Actress Saoirse Ronan (pictured above) attended Hollywood's premiere of her new movie The Host last night at ArcLight Cinemas. Ronan, who won critical acclaim for her work in 2007's Atonement, wore a sleek wine-colored dress from Lanvin for the occasion.

Diane Kruger (Troy, Inglorious Basterds), who came to the screening with boyfriend Joshua Jackson, opted to wear a black Thakoon dress.

Twilight and The Host author Stephenie Meyer attended too, ready for spring in a floral gown and bright red lipstick.

The Host, based on Meyer's novel of the same name, follows Ronan's character, Melanie Stryder, as humans become the physical hosts of invading aliens called Souls. When Melanie's body is inhabited by the alien Wanderer, both entities will begin a struggle for mental dominance, all the while trying to resolve feelings for Melanie's lover Jared and Wanderer's crush Ian. The Host hits theaters Friday, March 29.
