Amanda Bynes's mother is dropping her bid for conservatorship, TMZ reports, as she has a plan to get an even tighter hold on her daughter. The troubled star could remain at UCLA Medical Center for a year and a half.

After setting fire to a stranger's driveway in Thousand Oaks, Calif. this summer, 27-year-old Bynes, who had just become the source of widespread mockery and media scrutiny for her strange behavior and legal run-ins, was placed on a 5150 psychiatric hold by police. Her mother, Lynn Bynes, was at the time trying to get conservatorship over her daughter and her estate, and a California judge granted her this temporarily.

Bynes's long list of legal troubles includes a DUI, the case for which has been moved to a mental health court at the request of her lawyer, and illegal possession of marijuana.

Today, in a NYC court, Bynes's lawyer Gerald Shargel asked for his client's charge for allegedly throwing a bong outside of her apartment window to be postponed for up to 18 months while she continues her psychiatric treatment at UCLA.

Sources tell TMZ that the case will be plea bargained, and that due to weaknesses in the prosecution's case, it could be dropped altogether.

Meanwhile, Bynes's mother, Lynn, has dropped her bid for permanent conservatorship over her daughter, as doctors have given her the power to make medical and financial decisions for Amanda, who is on an LPS hold. Thus, there is no need for Lynn to bid for conservatorship anymore, so she has withdrawn her petition.

"Amanda has profound issues with her body image and is obsessed with the idea that she [and others] are 'ugly,'" her parents told a California judge back in August while they petitioned for temporary conservatorship. "She talks incessantly about cosmetic surgeries that she wants to have completed. We are concerned that the surgeries she wants to have are dangerous and detrimental to her health."
