Amanda Bynes Latest Shocker: Out of Control School Behavior Led to DUI?

Amanda Bynes is so out of control that her problems are only getting worse.

Amanda has been such a trainwreck at the Fashion Institute of Design and Merchandising in Irvine, California, that the school kicked her out last month.

According to TMZ, fellow classmates witnessed a high Amanda staggering into class every time she showed up which wasn't that often. One of those students, Rachel Loritz, told the site Amanda often "ditched classes ... but even when she showed up, she was clearly high, and not good at hiding it."

"She almost always wore sunglasses and laughed out loud at inappropriate times."

Rachel went on to say Amanda's mood would change causing her to get into "horrendous arguments" at school.

Things got so bad Amanda paid classmates to do her homework, but Rachel said no. Amanda was even cheating off of a fellow student, but made a huge scene when she was caught.

Amanda's craziness at school is not a shock due to her recent arrest for Driving Under the Influence. The Hairspray actress was pulled over by police Sunday morning after she was seen driving erratically. She failed field sobriety tests administered by the cops which led to her arrest.

According to E! News, a spokesperson for the California Highway Patrol said that, "Amanda was displaying symptoms that led us to believe she may have been under the influence of a stimulant. It possibly could be a combination of a stimulant and other drugs."

The drug, as per TMZ, was Adderall that had been prescribed by her doctor.

Is this the beginning of the end for Amanda or will she try to make another comeback?
