Amanda Bynes is currently under doctor supervision.
The very troubled young star - who accused her father of sexual abuse this week - landed today in Los Angeles and was immediately taken by a car service to a hospital on Pasadena.
Her attorney, Tamar Arminak, was waiting there for Bynes with a physician.
She is now being held on a 5150 psychiatric hold for 72 hours and sources confirm her parents are seeking a 14-day extension, during which time they will apply again for conservatorship.
Section 5150 is a section of the California Welfare and Institutions Code.
It allows a qualified officer/clinician to confine a person believed to possess a mental disorder that makes him/her a danger to himself or herself, a danger to others and/or gravely disabled.
Past stars to have been placed in similar situations include Britney Spears, Mischa Barton and Lindsay Lohan.
A few hours after accusing her father of sexual assault, Bynes took to Twitter this afternoon and retracted the statement.
"My dad never did those things," Bynes wrote on Twitter. "The microchip in my brain made me say those things but he's the one that ordered them to microchip me."
This isn't the first time Bynes has referred to a microchip. She told Life & Style just last week that people are "reading my mind."
The actress was also hospitalized on a psychiatric hold in 2013. This stint was followed by an extended stay in rehab, during which time her mother became her conservator.
She was then released into her parents' full-time care in December and appeared to be on a path to recovery.
However, Bynes was recently kicked out of her school and then she became estranged again from her mom and dad. Last month, she was arrested for DUI.
Amanda Bynes is clearly in need of major help. Let's hope she gets it.
