TMZ has confirmed that Mischa Barton has been arrested for DUI, possession of illegal narcotics and driving without a valid license.

The former “O.C.” star was pulled over early this morning around 3:00 AM as she was driving in West Hollywood, Calif., and is still in custody, being held on $10,000 bail. The Inmate Info doc called her “Mischa Burton.”

Mischa Barton is reportedly coming off of a recent stay at an Arizona rehab center … & according to paparazzi following the ex-OC actress, she hasn’t seemed to be able to stay sober for long.  Looks like art has imitated life from the small screen to Miss Barton’s real life.

Barton & a friend stopped by a low-income housing facility in Venice, CA earlier this week to supposedly buy marijuana.  When they returned to their car, they were observed sparking up a joint.

“Mischa appeared to be really enjoying the pot, taking long drags off of the joint before passing it to her buddy,” an onlooker tells.

After they got high, the group drove off to West Hollywood to take care of some last minute holiday shopping.

Let’s just hope Mischa remembered everyone on her list!

PS - WTF is up with her outfit???  That must be some good stuff she’s on …

I don’t know how I feel about the choice of wardrobe- what little there is- but the girl looks hot!

Maxim magazine’s January cover girl Mischa Barton has gon back to her golden locks -THANK GOD – in Belfast, Northern Ireland, on Wednesday. She’s in the Emerald Isle promoting her period drama Closing the Ring.

In her days since playing Marissa on The O.C., Barton says it’s been relatively easy to leave that part of her career behind her.  She told press, “Even if I was a precocious teenager, it’s a New York vs. L.A. thing. I never experienced the ‘anything goes’ chaos we sold on The O.C.  Marissa was a nut case. I didn’t have much in common with her. In New York I’d want to go out at 15 or 16, but I got it out of my system.”

She even helped conjure up the concept for killing off Marissa.  “You have no idea how much fun I had doing that [scene]. I was on the set, yelling, “More blood! More blood!” She needed to go out with a bang.”

Who’s she dating these days?

Hate the shoes, hate the hair!  What happened to Marisa?  Keds must have one hell of a contract to make her wear these voluntarily.

Guys, get out your napkins now to wipe away the drool. Mischa Barton is scheduled to be releasing her new movie “Closing the Ring” soon and guess what…Men will finally be able to see what she looks like underneath her clothes without a “wardrobe malfunction”. The movie is set to release sometime in 2007.

The film opens in 1943 when a dying gunner, who was in a crash involving a USAF B-17 Flying Fortress, gives a ring to a local to return to his girlfriend in the United States. Fifty years later, a man finds the ring and tracks down the girlfriend and the history of this ring.
