 Amanda Bynes’ erratic and disturbing behavior has taken a drastic turn for the worse because the starlet has been hearing voices and talks to herself in unintelligible sentences, RadarOnline.com is exclusively reporting. 
 
 The former Nickelodeon star has been “spotted wondering the halls of her New York City apartment building at all hours of the night. She talks to herself in language that in non-sensical and has been hearing voices. Amanda is also extremely paranoid and thinks there are tracking devices in the smoke alarms in the apartment. She looks completely disheveled and she is scaring some of the other residents in the building with kids,” a source told RadarOnline.com exclusively. 
 
 As RadarOnline.com previously reported, Bynes’ has also been smoking a lot of marijuana.

 “Amanda’s increasingly disturbing behavior is related to the fact that she smokes pot. It makes her more paranoid and instead of mellowing her out, it does the opposite. Amanda begins talking faster and just can’t seem to sit still,” an insider previously told us. 
 
 The 27-year-old starlet’s use of drugs has long been chronicled: When driving on a suspended licence in Sept. last year, Bynes was photographed puffing on what appeared to be a marijuana pipe, then, earlier this month, she was snapped on the streets of Manhattan smoking what appeared to be a marijuana cigarette. 
 
 Despite her increasingly concerning behavior, Bynes’ parents, Lynn & Rick, are “powerless to do anything” to rescue her. 
 
 “There are no legal options available to them to help rescue their daughter at this time,” the insider added. 
 
 
 

– 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.
