More problems for actress Natasha Lyonne.

Once again, Natasha Lyonne is a wanted woman for all the wrong reasons.

The onetime American Pie star, who has publicly fallen on hard times in recent years, has yet another warrant out for her arrest, after she failed to appear at a court date Friday, the New York Post reports.

Lyonne is facing a number of charges, including her alleged threat to sexually molest her former neighbor's dog during a 2004 altercation. She is also charged with criminal mischief, harassment and trespassing.

Friday's hearing was rescheduled after the actress missed court dates earlier in the week. Last Monday, her lawyer explained to the judge that "an emergency has come up." The lawyer went on to confess that he did not know what the emergency was.

The latest absence marks the fourth time Lyonne has missed a court date and the third time a bench warrant has been issued for her arrest.

The most recent warrant against the troubled actress was cleared up after it was revealed she spent most of the summer being treated at a New York hospital for hepatitis C, a heart infection and a collapsed lung.

Per the Post, the actress was also receiving methadone, a drug commonly used to combat heroin addiction. A source familiar with the case told the newspaper that Lyonne's arms were covered with needle tracks at the time she was admitted to the hospital.

Lyonne reportedly entered the hospital following a stint at a psychiatric facility. Before that, she was believed to be living on the street, according to the Post.

"I'm crying actually. It's terrible, you know. It's my little girl," Lyonne's father, Aaron Braunstein, told Access Hollywood at the time. "It's a terrible tragedy, but she's going to get better. We're praying for her, and she's a tough girl."

The actress recovered sufficiently to leave the hospital but has apparently returned to her prior address of whereabouts unknown. . . . . . .Source
