After her first meltdown last year, Amanda Bynes was placed under a conservatorship that put in her parents care by court order.
By the time it expired, Amanda's folks apparently believed she had made enough progress that she could be trusted live independently.
Oh, how wrong they were. Bynes was arrested for DUI last week, and her behavior has been growing increasingly bizarre and erratic ever since.
She's been spotted talking to herself and crashing her bike into pedestrians in Manhattan, and just yesterday, Bynes claimed to be engaged to a 19-year-old named Caleb, who her friends and family believe is a figment of her imagination.
Sources say Amanda's mother - Lynn Bynes - now recognizes the need for an intervention, and she's reportedly headed to NYC in an effort to convince her daughter to check into a rehab facility.
Unfortunately, it looks as though it may be a case of too little, too late.
Amanda has been tweeting again (during her last public breakdown, her nonsensical online ramblings frequently made her a trending topic), and her posts seem to suggest that she thinks she's doing just fine.
"The only reason Lynn hasn't hopped on a plane sooner is that even if she does fins Amanda, there is very little she can do to bring her back to Southern California," a source tells Radar Online.
"The conservatorship ended in August and Amanda has been on her own ever since then. Lynn now realizes ending the conservatorship was a huge mistake."
Amanda's parents can only request a renewal of the conservatorship if they are able to prove that she poses a clear threat to herself or others.
If Amanda is in any way injured or causes harm to somebody else, sources say her parents will petition the court immediately.
