Amanda Bynes 'spoke to herself in unintelligible sentences'

Amanda Bynes has reportedly been "talking to herself in nonsensical language" for months.

The 27-year-old former child actress has been hospitalized for psychiatric evaluation after allegedly setting a fire in a Los Angeles suburb on Monday night, Radar Online reported.

A source told the publication that Bynes' neighbours often heard her walking in communal areas speaking a "nonsensical" language.

According to L.A. Times, she would be subject to the two-week hold, if mental health authorities determine she's a danger to either herself or others.
