A Los Angeles court has again extended Amanda Bynes' involuntary psychiatric hold, this time for an additional 30 days.

TMZ.com said Tuesday that a judge ordered the extension after doctors on Monday told the court Bynes, 28, is "very ill" and in no condition to care for herself. She was admitted on Oct. 10 to Las Encinas Hospital in Pasadena, California, under a state law permitting a 72-hour involuntary hold that can then be extended. A judge on Oct. 13 had granted an additional two weeks.

Bynes had been involuntarily hospitalized in July 2013 after police found her setting a small fire in a stranger's driveway in Thousand Oaks, California. After four months of inpatient rehabilitation, she was released to her parents, Lynn and Rick Bynes, under her mother's conservatorship. In April this year, she denied, through her attorney, that she suffered from schizophrenia.

It was unclear Tuesday whether her parents planned to pursue a new conservatorship or seek to have Bynes remain hospitalized in treatment. Bynes' attorney did not respond to a Newsday request for comment.

The former star of Nickelodeon's "All That" and "The Amanda Show" has exhibited much troubling behavior in recent years, including being arrested for DUI in 2012, for which she was convicted in February. She was also arrested in Manhattan last year on unlawful possession of marijuana and reckless endangerment charges that were dropped conditionally in June.

The current psychiatric hold came after another DUI arrest last month, a string of tweets earlier this month in which she accused her father of abuse, later recanting but saying he implanted a microchip in her brain, and a reported shoplifting incident in Manhattan.
