Just four months after leaving a rehab facility, formerly troubled actress Amanda Bynes appears to be back to her formerly healthy and happy self.

Although Amanda Bynes remains locked down under a 5150 mental health hold, fellow All That star Nick Cannon is thinking about her every day and has high hopes about collaborating with the troubled actress on upon her release.

Amanda Bynes remains under psychiatric hold (for up to two weeks) following a hearing at the hospital where the actress has been under evaluation since last week. Her Twitter has fallen silent, but let's take a look back at her most bizarre Twitter photos.

Amanda Bynes is constantly throwing insults to celebrities, calling them all "ugly," but the troubled actress may have gone too far with her latest tweet.“Not having hair makes me feel like a cancer patient,” she tweeted.Lots of people were understandably upset by the comparison. Realizing that she had made a huge mistake, Bynes removed the offending tweet and issued an apology for the error. According to the retired actress, the whole fiasco was caused by a simple grammar mistake.
