Kristen Stewart  and Taylor Lautner  attended a concert together at The Troubadour in LA last night. Kristen and Taylor dropped by the venue with a group of friends — including Katy Perry 's assistant, Tamra Natisin, whom Kristen hit the town with on Sunday — to see Marcus Foster perform. Marcus has been a longtime friend of Kristen's and she even starred in his "I Was Broken" music video  back in 2011. Noticeably absent from the bunch was Robert Pattinson , who is currently filming The Rover in Australia. Rob is also close with Marcus, and even sang the musician's song "Let Me Sign" for the Twilight soundtrack back in 2008.
This isn't the first time that the two Breaking Dawn stars have hung out since filming wrapped: Kristen celebrated Taylor's 21st birthday  with the actor back in February.
