The troubled life of Natasha Lyonne has taken a tragic turn.
The American Pie actress is in intensive care at a New York City hospital with hepatitis C, a collapsed lung and a heart infection, according to Access Hollywood and the New York Post.
The 26-year-old actress, who hasn't been seen publicly since a judge issued a warrant for her arrest in April after she ducked a court hearing, is reportedly "fighting for her life" and "struggling to survive," per Access Hollywood.
"I'm crying actually. It's terrible, you know. It's my little girl," Lyonne's father Aaron Braunstein told the syndicated show Friday. "It's a terrible tragedy, but she's going to get better. We're praying for her, and she's a tough girl." Visit for more:
The Post reports that the actress is also receiving methadone treatment, which is typically used to combat heroin addiction.
It's not clear if Lyonne has been using the drug, but according to a Mayo Clinic report, the primary mode of transmission of hepatitis C is via contaminated blood--through needles shared by drug users or through blood transfusions. The disease can lead to potentially serious liver damage.
Braunstein, who told Access Hollywood he visited his daughter last week, says he thinks Lyonne may have picked up the virus while shooting a movie abroad three years ago.
"She's probably with the wrong crowd," he said. "The main thing, she picked up the liver thing in Bulgaria during [filming of] The Grey Zone."
Lyonne, whose credits also include Slums of Beverly Hills, Party Monster and last year's Blade: Trinity, has not had a publicist or Hollywood representation for the past several months, which have been a rough stretch for the actress.
She was charged in December with criminal mischief, harassment and trespassing after she purportedly melted down on her New York neighbor, ripping a mirror off the woman's wall and threatening to sexually molest her dog.
Lyonne had been due in court Apr. 19 to answer the charges but left the courthouse early, prompting Manhattan Criminal Court Judge Abraham Clott to put out an arrest warrant.
The Post claims that Lyonne was subsequently evicted from her apartment and wound up living on the streets before turning up in the city's Bellevue Hospital. She was then transferred to Beth Israel Hospital, where she is currently admitted under a pseudonym, according to the Post. Neither hospital has confirmed Lyonne's patient status.
Speaking to Access Hollywood, her father disputed the report that Lyonne was homeless and suggested he might take legal action against the paper.
"There's a confidentiality between patient, doctor and hospital, so all of this is probably going to be a major lawsuit," he told the show.
Lyonne previously pleaded guilty in 2002 to a DUI charge in Miami. She was sentenced to six months' probation for the incident, which involved fleeing the scene of a car accident.
She last starred in the indie comedy Max & Grace, about a suicidal couple who break out of a mental institution. The film premiered at South by Southwest in Austin in March and has been making the rounds on the festival circuit but has not yet been picked up by a studio.
