Mischa Barton had a rough night over the weekend in Hollywood. A spy reports that the “O.C.” actress, who alternates between being on and off the wagon, rolled into Bar Marmont on Saturday alone and looking “totally out of it.”
Says our witness, “A few minutes after she comes in, she runs outside and vomits everywhere. And then she went back inside and hung out for the rest of the night.” A rep for Barton declined to comment.
