Mischa Barton and her younger sister Hania seem to be in some weird competition for who can have the most messed up life. And it’s really hard to tell who’s winning most of the time. But it seems like, more often than not, 19-year-old Hania is generally ahead. She’s reportedly been in rehab several times since her mid-teens. Mischa’s always been reported to be somewhat of a self-centered, drinking-too-much b****, but didn’t seem to truly be in the running for the “Most Messed Up Barton” until she got a DUI right after Christmas. What was left of her struggling career seemed like it would definitely end up in the toilet. But at least she had more of mom and dad’s attention right? Well it appears that a mere hours after Mischa was let out of jail, Hania overdosed on muscle relaxants. That’ll teach you to pay more attention to the older sister.

Mischa Barton’s younger sister Hania has suffered a drug overdose in an alleged suicide attempt on the same day The O.C. star was caught drink driving. Reports posted online by Perez Hilton and the National Enquirer state that Hania Barton, 19, was rushed to Los Angeles’ Ceder’s Sinai Medical Center on December 27th suffering convulsions.

A source told the National Enquirer tabloid, “The family bodyguard found her obviously overdosed on drugs, c alled her mother, and then rushed Hania to the emergency room. It was a suicide attempt, and by the time she got to hospital, Hania was absolutely hysterical.”

The Enquirer also claims mini Barton confessed to overdosing on the muscle relaxer Soma; was treated for six hours before insisting on being discharged. She was accompanied by her elder sister Mischa, who just twelve hours earlier was arrested for driving under the influence and possession of drugs.

Mischa has recently hired two new publicists Howard along with lawyer Anthony V. Salerno, who worked with Isaiah Washington during his whole Grey’s Anatomy scandal. As part of her new PR routine, she went on Ryan Seacrest’s show this morning to talk about how bad she is.

“I got a DUI when I was back in LA,” she said the Dec. 27 incident. “I was pulled over. Obviously, I am 100 percent responsible for my actions, and I am really disappointed in myself. I am not perfect, and I don’t ever intend to do something that stupid again.”

The 21-year-old former star of The O.C. acknowledged she doesn’t have a valid license: “I usually try not to get behind the wheel.”

“It is tough when people are talking about you all the time,” she told E! News anchor Seacrest. “You just have to roll with it. I feel like I’ve got my head on my shoulders pretty good.”

I don’t buy it for a minute, but at least she’s smart enough to hire publicists. Remember about two years ago when Britney Spears fired hers? Brit thought she could do a much better job of spinning her shenanigans than the pros. Didn’t exactly work out like she’d hoped. At least Mischa is smart enough to know she’s not that smart.
