Clad in a dress from her Spring 2011 L.A.M.B. collection, Gwen made it to the front of Sephora a little past 10 p.m. Outside, people began scaling the walls for a peek, so G and her Harajuku Girls dancers stepped into the window for a quick hello. Gwen was tweeting away throughout the evening, and yes, she handles the No Doubt account herself. ("Who else would do it?" she asked.) More from Gwen soon, but for now, check out these pictures from the event.
