Mischa Barton Is Bitchy

We can’t say that we’re shocked.

“You’re so [bleeping] retarded!” the magazine reports Mischa told her mom, when she had trouble working the Ritz’s elevator key. “What idiot can’t put a [bleeping] key in? You’re so stupid — it takes you 10 hours to do anything!”

But Mama Barton took it all in stride. “You’re mad about something that has nothing to do with me,” she said sagely. “Stop with the attitude!”
