Natalie Portman left a friend's house solo in LA yesterday. She was dressed for the warm West Coast weather in denim shorts and sported her new lighter locks. Natalie debuted her blond hair over the weekend when she attended the Van Cleef & Arpels Dinner for LA Dance Project. Natalie dined with husband Benjamin Millepied at the event and also posed with Robert Pattinson on the red carpet. Rob partied with Dita Von Teese as well, since his girlfriend, Kristen Stewart, wasn't on hand. Natalie will soon get back in front of the cameras for an untitled Terrence Malick project, which her costars Ryan Gosling and Rooney Mara were spotted filming in Texas this week.
