A judge has extended Amanda Bynes' psychiatric hold for up to two weeks following a hearing at the hospital where the actress has been under evaluation since earlier this week.

At the same time, her parents are now trying to take legal control of the actress's life.

TMZ reported that late Thursday that Rick, 68, and Lynne Bynes, 66, have filed an application for conservatorship over their daughter. A hearing is reportedly set for Friday morning.

As EnStars previously reported on Monday, Bynes was hospitalized on a 5150 hold -- a 72-hour involuntary hospitalization during which the individual in question undergoes a mental health evaluation -- after she allegedly set fire to a stranger's driveway.

"Amanda Bynes was involved in a disturbance in a residential neighborhood last night in Thousand Oaks in the 200-block of Avenida De Los Arboles," Captain Don Aguilar of Ventura County Sheriff's Office told EnStars in a statement. "Deputies investigated the incident and determined that she met the criteria of 5150 W&I (California Welfare & Institutions Code). She was detained and taken for a mental health evaluation. Ventura County Fire Dept. also responded to this incident in reference to a report of a gas can on fire in a driveway."

On Thursday, sources told TMZ that doctors have determined Bynes is suffering from a severe mental illness "with schizophrenic tendencies."

"There's a good Amanda and a bad Amanda," the source said, adding that Bynes was good for about ten hours before she had a meltdown. She allegedly "got incoherent and so out of control she had to be physically restrained," the source said.
