Keira Knightley wore an embroidered Valentino dress last night for the LA premiere of her new comedy, Seeking a Friend For the End of the World. The screening, part of the Los Angeles Film Festival, brought out a pregnant and newlywed Drew Barrymore, as well as the movie's leading man, Steve Carell, and writer-director Lorene Scafaria. Lorene's screenplay is a funny look at what people would do when faced with the imminent destruction of the world by an asteroid. Keira, for one, wouldn't alter her fashion choices. Keira would forgo wearing sweatpants if she endured what her character goes through. She'd actually dress up! Keira said, "This is a good end-of-the-world dress, actually; I was thinking that when I put it on. It's quite comfy as well . . . I don't really own any sweatpants, actually." The picture comes out in the US on June 22.
