OD For OC Star's Sister?

Mischa Barton's DUI undoubtedly threw her family into chaos back on December 27th - but now we're hearing that it might not have even been the worst blow the Bartons endured that evening!

The National Enquirer is reporting that Hania, Mischa's little sister, was rushed to Cedars Sinai on the 27th for a drug overdose following a suicide attempt!

"The family bodyguard found her obviously overdosed on drugs, called her mother, and then rushed Hania to the emergency room," the Enquirer quotes a source as saying. "By the time she got to the hospital, Hania was absolutely hysterical."

The Enquirer's source is also very specific on one point, referring to Hania's alleged overdose as a "suicide attempt".

Other claims made by the magazine include that Hania OD'd on Somas, received only six hours of treatment before being discharged, and that she was accompanied by her big sister - only twelve hours after Mischa had been arrested for DUI and possession of drugs!

Don't forget, Hania spent some time in rehab last year - in fact, the picture accompanying this article comes from a story we did on her first day back last year.

It would be sad enough news to hear that she fell off the wagon - but to hear that she OD'd takes it to a whole new level!
