The 23-year-old actress was taken to Los Angeles' Cedars-Sinai Medical Center for psychiatric evaluation, with her publicist Craig Schneider recently confirming she is still at the hospital.
Friends of Barton, who did not attend the New York premiere of her new movie 'Homecoming' Thursday, recently claimed she was on a 'destructive path' of drug use, and believe it will take her a long time to fully recover.
'She is a tortured and troubled person. You can survive a bad review, but when you don't show up for the premiere of your new film, it's not a good sign of where your career is heading,' said a friend.
