Kristen Stewart looked casual as she left Robert Pattinson's London home this morning. Breaking Dawn Part 1 finally opened in theaters at midnight following a busy Twilight promotional tour over the past few weeks. Kristen joined Robert Pattinson for the LA premiere of Breaking Dawn on Monday and the duo made the talk show rounds as well. They sat down on The Ellen DeGeneres Show to chat "baby-making" and Kristen also opened up about her intense big-screen moments to Jimmy Kimmel. Rob is currently continuing work for the series and he popped up with Taylor Lautner in Spain just yesterday. Kristen, meanwhile, has switched gears to her next project, Snow White and the Huntsman. She's been back on set for the fairy-tale reboot with costar Chris Hemsworth, whom she says she has become "really close" to since filming started.
