Amanda Bynes has been placed on psychiatric hold for the second time, a source confirms to Us Weekly.
After landing in L.A. on Friday, the troubled star was apparently taken to a treatment facility in Pasadena, California, where she will be held for 72 hours, according to TMZ.
The move happened on the heels of Bynes's increasingly bizarre behavior in New York City, culminating in a series of disturbing tweets directed at her father.
The allegations led the troubled actress's mother to break her silence and come to his defense on Friday.
"I am heartbroken today for my husband of 47 years," Lynn Bynes told Yahoo in a statement from her attorney, Tamar Arminak. "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."
