Jennifer Aniston Pictures in White at London Horrible Bosses Premiere

Jennifer Aniston changed from black leather into something white and ladylike for this evening's London premiere of Horrible Bosses. Her frock was Valentino, paired with Tom Ford shoes. She's in England at the moment doing press for the dark comedy, which arrived in theaters in the US earlier this month. Her costars Kevin Spacey, Charlie Day, Jason Sudeikis, and Jason Bateman are all along for the trip, but so far there's been no sign of her real-life leading man, Justin Theroux.
