Mischa Barton is being sued for over $300,000 by producers of a movie she was supposed to work on.
The 28-year-old actress - who hasn't had a successful acting project since the 'O.C.' ended in 2006 - is the subject of a lawsuit from the producers of movie 'Promoted' who claim she missed working on the film because she was partying in Europe.
According to legal documents obtained by TMZ, movie bosses attempted to contact Mischa about a March 4 start date and sizing her costumes but got no response.
The day before they were due to begin work, the actress' mother sent an email which read: "Mischa is still in Europe and won't be available until the 20th of this month."
And the company then saw several posts on the actress' social media accounts which revealed she was on vacation and partying in Italy, as well as "enjoying tourist excursions with friends."
As a result of Mischa's absence, the lead actor didn't want to work with another actress, causing more problems for the production.
Producers are suing their former star for her $20,000 advance, $200,000 in marketing expenses and $100,000 which they say they will lose because she is no longer attached to the film.
The legal battle is the latest problem to hit Mischa as it comes just weeks after it was reported she is close to losing her home.
The eight-bedroom Beverly Hills mansion - which is worth over $8 million - has been placed in foreclosure after she failed to keep up with her mortgage repayments for the last five months, leaving her $100,000 in arrears.
