You may know her as "Anna" from The O.C. -- well, that's how I know her -- or from her gig on Entourage, but either way, actress Samaire Armstrong is fighting some emotional battles. Samaire has entered an outpatient facility for what is being called "personal issues," but will continue her work on her new show, Dirty Sexy Money. The nature of the demons she is fighting was not revealed. Any guesses? Drugs, booze, eating disorder, depression?
