Mischa Barton’s little sister Hania, 19, who has already done a stint in rehab, showed up to work as a model at the Troy Kingdom fashion show but was fired on the spot, according to Celebritybabylon.com. A source said she was so wasted that she could “barely stand up. Her legs were like jelly. She was literally chewing on her lower lip.” When someone tried to take a picture, she freaked out, screaming: “No pictures! That $h*t about me always ends up in the tabloids!” She then fell asleep on a chair.
