Amanda Bynes' involuntary hold has been extended for another 30 days

Los Angeles - Amanda Bynes will remain in hospital for another 30 days.

Doctors treating the Easy A star, who was committed to a psychiatric treatment facility in Pasadena, California 17 days ago, secretly convinced a judge on Monday to extend her involuntary hold because the 28-year-old star is still "very ill" and unable to take care of herself.

If the extension wasn't granted, the blonde beauty could have walked out of the hospital on Monday, according to gossip website TMZ.com.

Meanwhile, Amanda's parents, Lynn and Rick Bynes, are said to have had a change of heart and are no longer sure whether they want to go back to court to regain a conservatorship over her because she feels betrayed by them for arranging for her to be taken to hospital, shortly after she was arrested for driving under the influence [DUI] and accused of shoplifting.

Amanda spent five months in a treatment facility in July 2013 when she was placed under involuntary psychiatric hold.

She was released in December and appeared to be getting her life back on track until a conservatorship giving her mother control of her affairs came to an end last month.

Another source recently revealed doctors may go to court to obtain an LPS hold, which would allow medics to confine her to hospital or another secure facility and administer medication against her will and lasts up to 12 months.
