I have to say, this is a real disappointment! I didn't know she was a druggie. Young Hollywood is a mess! Oh mush mush! What not so talented actress and spokeswhore created a huge scene at a Memorial Day house party on Sunday at the home of Nicole Richie's best friend? Apparently, she did so many mushrooms - in addition to a lot of cocaine - that she thought she was dying! What a fart-tastic way to ring in the holiday. Update: TMZ has confirmed our scoop, though they're claiming Mischa suffered an allergic reaction to antibiotics and alcohol. Our sources inside the party insist it was much more than just alcohol and antibiotics. Fartone was rushed by paramedics out of the party in a stretcher, sources tell PerezHilton.com exclusively. "It was total chaos," says one partygoer. Mushy is currently in the hospital. Who is rushed to the emergency room from too much alcohol and antibiotics???? No one!
