Mischa Barton's landlord says the actress is refusing to pay rent on her $7,000-a-month apartment in New York City. Landlord M.R.A. Realties Inc. says in a lawsuit that Barton rebuffed efforts to collect the last three months' worth of rent on her flat in the trendy Tribeca neighborhood.

Barton's representatives had no immediate response. The landlord wants the 23-year-old actress to pay the rent and legal fees.
