(Mar. 7, 2006 12:40PM ET) -- Mary-Kate Olsen's strange behavior at a post-Oscars party Sunday night is raising questions. Our TMZ camera caught Mary-Kate in the fetal position in the back seat of her limo as she was driven away from a private party at the Soho House in the Hollywood Hills.
TMZ also captured this video of 19-year-old Mary-Kate entering the club Mood in Hollywood last month. It's illegal for the club to allow anyone under 21 inside. We don't know if Mary-Kate was drinking or teetotaling.
In 2004, Mary-Kate's reps acknowledged she had been admitted to an undisclosed facility for an eating disorder. Video
