The O.C. alum is the only Season 1 cast member not invited back for The Hills revival's second season, reports TMZ, which adds: "The reason ... our sources say producers found Mischa's story line a bit bland, and her personality a little boring. Bottom line, she wasn't bringing much drama to the show."
