Former OC actress Mischa Barton, who was hospitalised last year for psychiatric observation, has now been sued for back rent on her New York apartment.
Her landlord, MRA Realties Inc, accused Barton, 23, of neglecting to pay three months rent on her $US7,000 a month apartment in New York's TriBeCa neighbourhood, owing $US21,300, according to the lawsuit filed on Thursday in New York State Supreme Court in Manhattan.
British-born Barton failed to pay rent from November 2009 through January 2010 on her year-long September 2009 lease, and owes an additional $US100 for each missed month, the suit said.
The apartment has been vacant since November, said Joseph Burden, the landlord's attorney.
A representative for Barton, who was the star of youth drama The OC from 2003-2006, said he had no knowledge of the suit.
Barton initially moved from Los Angeles to New York to film The Beautiful Life for the CW network, but the show about a group of fashion models was canceled after only two episodes.
She was in New York for the last week and a half filming Law and Order: SVU, Barton's representative said.
