UPDATE - Amanda was basically tricked into going to a hospital outside L.A. where she's been placed on an involuntary 5150 hold. Amanda thought a car service was taking her to the London hotel to meet with her parents and their respective attorneys, but the 'rents flipped the script and had the car take their daughter to a psychiatric facility, according to TMZ.

She'll be held for 72 hours and the stay could be extended for as long as two weeks. Bynes' parents will try to get another conservatorship.

She's baaaaack!

Amanda Bynes touched down at LAX this afternoon, and it appears she was successful in catching a last minute flight after getting kicked out of LaGuardia airport earlier this morning for screaming at a ticket agent in a frantic attempt to flee the Big Apple.

In case you missed it, the troubled starlet went on a Twitter rant today and accused her father of incest and abuse, before taking back her comments and blaming her outburst on "the microchip in my brain [that] made me say those things". Her alarming accusations prompted her mother Lynn to come to her husband Rick's defense in a statement issued by their attorney.

"I am heartbroken today for my husband of 47 years. Rick has been the best father and husband a family can ask for. He has never abused Amanda or our other children physically or sexually. These accusations are absolutely horrible and could not be further from the truth! These allegations stem from Amanda's mental state at the moment. They have no basis in reality. It saddens me beyond belief that my husband's character could be slandered in such a way," the statement read. Amanda's brother and sister also issued their own statement to defend their father.

It is said that the family is desperate to get the 28-year-old into a treatment facility, but her next move now that she's back in Los Angeles remains to be seen. Stay tuned for all the updates...
