Mischa Barton’s parentals think she’s running with a bad crowd and headed for rehab. I think that I’m not sure why this biddy is in the news so much. I saw one episode of “The O.C.” and this chick isn’t an acting dynamo. Her best role was as the child vomit ghost in “The Sixth Sense”. And she’d didn’t have many lines and just had to look dead.

The former ‘O.C’ actress’ parents are worried their 21-year-old daughter – who recently collapsed after accidentally mixing antibiotics with alcohol – could follow in the footsteps of some of the troubled stars she has been partying with including Lindsay Lohan, who checked into rehab last week.

A source told Britain’s Grazia magazine: “Mischa’s family is worried she is hanging around with the wrong kind of people because a lot of them are headed to rehab.

More on Mischa and her family’s worries after the jump.

“Mischa doesn’t really hang out with her old friends the way she used to and the people she’s been spending time with – Lindsay, Paris and Nicole – have them totally freaked out.

“The last thing her family wants is for her to turn into some Hollywood party girl.”

Uh, once you take some bad acid and roll under a damn picnic table at your celebrity friend’s Memorial Day bbq screaming that Satan’s coming to kill you, well you’re past “party girl” and onto “drug casualty”. Freedom Rock, turn it up!
