Britney Spears headed to LA's Troubadour club with Jason Trawick last night. Her routine's been pretty low-key lately with daytime shopping trips and gym visits, but she switched things up for the evening out on the town with her boyfriend. Britney has a lot to celebrate with the progress of her new album and her recent People's Choice Award nomination for her guest spot on Glee. She's heading back into the studio tomorrow, though, to record what her manager calls a "big, big, big new song."
