X17 Xclusive - March 11, 2010: We spotted young actress Kristen Stewart (exclusive) and rock legend Joan Jett celebrating at Cabana with Taylor Lautner (exclusive) and Dakota Fanning after the Hollywood premiere of "The Runaways." Dakota remained in her sequined dress and stopped to sign autographs, but Kristen got casual, dashing into Cabana wearing a t-shirt and jeans and dodging fans.
