Amanda Bynes Locks Herself In Dressing Room

There's more bizarre behavior coming from Amanda Bynes as the troubled starlet locked herself in a clothing story dressing room for 2 hours. INSIDE EDITION has the scoop.    

Amanda Bynes' downward spiral just took a bizarre twist. She barricaded herself inside a dressing room at an upscale boutique and refused to come out for a full two hours.

Bynes was photographed shopping at 'Kin' on Sunset Boulevard in West Hollywood.
After selecting a jacket, a white t-shirt, and a fox tail scarf, Bynes entered a dressing room and barricaded herself inside for nearly two hours.

When Bynes finally left, she covered her face with her fur scarf and got into a cab, and you won't believe what happened next. Bynes was driven to a Starbucks and locked herself in the bathroom for 15 minutes. A Starbucks employee escorted her out of the store.

It's just the latest in a series of crazy behavior by the former Nickeleodeon star who rose to fame on The Amanda Show and the film Easy A.

Yet another sad chapter for an actress once considered one of hollywood's most promising young stars.
