The troubled Hairspray star stepped away from social media in early January (15) after posting a series of ranting tweets, but she was back online on Monday (16Mar15), showing off her artwork - a pencil drawing of a sad young woman, which resembled the former child star. She added the caption, "Hey my loves! Here's a drawing I did!

A previous tweet Bynes posted in December (14) suggested she was planning to become a student at the University of Southern California in Los Angeles.

She wrote, "I took a USC campus tour yesterday it was sick! I plan on transferring from FIDM (Fashion Institute of Design & Merchandising). The campus is sick (good)!"

Bynes, who completed spells in rehab 2012 and 2013, is scheduled to attend a court hearing to evaluate her behaviour and progress in June (15).

Meanwhile, reports suggest the actress has been posting tweets from a secret Twitter account under the name Ashley Banks.
