Uh oh…if Mischa Barton doesn't cough up $100k stat, she'll lose her $6.4 million dollar Beverly Hills mansion.
Mischa bought the gorgeous eight-bedroom pad back in 2005, at the height of her O.C. fame.
To her credit, Mischa tried to sell her swanky crib multiple times over the years but unfortunately she couldn't find a buyer.
We hope Mischa settles this matter as soon as possible…girl doesn't need any more drama in her life!
