Mischa Barton Charged With DUI and Pot

OMG, Mischa! DUI? And P-O-T? WTF?

Yesterday, the Los Angeles District Attorney's Office charged Barton with misdemeanor charges of driving with a blood-alcohol level of .08 or higher, driving without a valid license and possession of 28.5 grams or less of marijuana.

The charges stem from Barton's early-morning arrest in West Hollywood on December 27, after officers observed her Range Rover straddling two lanes and pulled her over.

The former OC star appears to be contrite. "Obviously, I'm 100 percent responsible for my actions in this case, and I'm really disappointed in myself," Barton noted on Ryan Seacrest's morning radio show.

Don't worry, Mischa; even if you are found guilty of all charges, you'll probably spend about 23 minutes in jail. Then you'll BRB on the S-T-R-E-E-T.
