Mischa Barton will accept a plea deal in her DUI case, sparing her any jail time. The former O.C. star will plead no contest to DUI at her arraignment Thursday in Beverly Hills court, and agree to serve a three-year unsupervised probation term, the source says.

Barton will also be sentenced to a three-month alcohol-education class, and pay a fine of approximately $1,700. In addition, a marijuana possession charge against the actress will be dropped, due to the small amount found. Another charge of driving without a license will be reduced to an infraction, according to the source.

So basically Mischa's getting away with everything. She needed to grow some balls and spend a couple hours in jail instead of taking the plea deal. It would've totally helped her career and at this point, I think she needs it!
