Amanda Bynes took a sharp downward spiral in 2013 when she started calling celebs from Drake to Miley Cyrus "ugly" and appearing (via selfless and paparazzi shots) in giant blonde wigs, cheek piercings, and a slightly shaved head. Bynes was arrested for throwing a bong out of the window of her 36th floor apartment. A few months later, Bynes was arrested for setting a fire in a stranger's driveway. After being hospitalized under a 5150 hold, Bynes entered rehab. She was released in December.
