Amanda Bynes Shaves Half Her Head

The latest stop on the road to crazy taken by Amanda Bynes: She shaved off half of her hair. "I buzzed half my head like @cassie! No more old photos! This is the new me! I love it!" she tweeted last night, along with a couple pictures. Making matters worse, a recent report in Radar has her "hearing voices" and talking to herself "in language that is nonsensical" while wandering around her New York City apartment building in the middle of the night, according to a source.

"She looks completely disheveled and she is scaring some of the other residents in the building with kids," says the source, who adds that the paranoid star believes the smoke alarms have tracking devices inside. That paranoia could have something to do with all the pot she's smoking, another source says. (More Amanda Bynes stories.)
