Kristen Stewart wore a pair of flip-up glasses while out and about in Berlin on Monday. Last week, she got back to work on the set of her new film, Sils Maria, after indulging in a bit of downtime with her friends in Berlin. She's stationed overseas, filming her latest project, for which she is sporting new ink. Kristen first showed off her new tattoo on her right forearm when she reported to work on her Berlin set. Her new project has several ties to her ex-boyfriend Robert Pattinson — Kristen's costars include Juliette Binoche, who played Rob's love interest in Cosmopolis, and Tom Sturridge, who is one of Rob's best friends. The actress recently jetted out of LA amid rumors of rekindling a romance with Rob.
