Bynes had allegedly attempted to get into the center in Thousand Oaks, but management turned her away for being drunk and trespassing. The retirement community called her a cab, but when Bynes got in, she told the driver, "Get me the f--- out of here. ... I don't have any money," TMZ reports. Bynes was then reportedly kicked out from the cab and returned to the retirement community. The cops were then called, but there is no record of her getting arrested. However, that doesn't exclude the possibility that Bynes was ticketed. The cab driver told the website that Bynes may have been attempting to visit a relative at the community.Britney Spears was held under a 5150 hold after locking herself in a bathroom with her son Jayden.
