Amanda Bynes was reportedly kicked out the Fashion Institute of Design and Merchandising for bad behavior last month.
Rachel Loritz, an alleged classmate of the troubled starlet, told TMZ Bynes often skipped class and attended lectures high on marijuana. The former Nickelodeon star reportedly wore sunglasses during lectures, laughed out loud at inappropriate times and got into "horrendous arguments."
Loritz added Bynes offered to pay fellow students to do her assignments for her and "threw a fit" after being reprimanded for cheating on a test.
Reports of Bynes' troubling behavior at school come one day after the former actress was arrested for DUI in Los Angeles.
The She's the Man actress completed a stint in rehab in December 2013 following months of erratic behavior online and multiple encounters with the law.
