Mischa Barton Pukes and Thinks of Cisco Adler

Mischa Barton is classy. She was half naked in the bathroom at Nicole Richie’s party. Nicole is awaiting a hearing on her latest DUI. No word as to why she was missing most of her clothes, but rumor is she puked all over herself. No doubt those clothes are being sold on Ebay. Here’s more:

Mischa Barton had "an allergic reaction" after combining antibiotics (which she was taking for bronchitis) with booze, according to her publicist, who vouches that her client was not among guests said to have been munching mushrooms at Nicole Richie’s party.

Barton did spend over a half hour in the bathroom at the party. And she was in a state of undress when she arrived at the emergency room, according to a source.

Barton’s parents met her at the hospital. "They were angry about her condition," says a spy. "When they left the room, she ran to the phone and tried to call Cisco Adler," whom she supposedly broke up with several months ago.

"Her dad came back into the room, and heard Mischa deliriously saying, ’Cisco,’ " says our source. "Her dad freaked out. She put the phone down, but he yelled at the staff about letting her use the phone."

It’s good to know Mischa’s parents realize Cisco Adler (mister nuts on the floor) is bad for their daughter like drinking Drano, but you can’t stop obsessive compulsive love without medication and rehab.
