Embattled star Amanda Bynes' lifestyle and living conditions have been exposed by editors at a U.S. tabloid, thanks to two sneaky snappers who attended one of the Hairspray star's recent all-night parties. The actress' mental health has become a talking point in recent months following a series of traffic violations in Los Angeles and some bizarre behaviour on the streets of New York, where Bynes has been photographed wandering around with a shirt over her head. She has also hit the headlines for tweeting odd messages about her romantic feelings for rapper Drake and she even posted 'selfie' pictures of herself topless on Twitter. Bynes has constantly defended herself from media attacks and rumours suggesting she is taking drugs, but the latest pictorial evidence in America's In Touch appears to suggest she's spiralling out of control. A photographer the publication, identified only as Joe, attended a party at Bynes' New York apartment and found the place to be sparsely furnished and filthy in places. He and another snapper, Giovanni Arnold, took shots of Bynes, who appeared to be happy to pose for them. Sporting her peroxide blonde hair, cheek piercings and dark sunglasses, the actress was snapped smoking what looked like a joint in bed and Arnold tells In Touch, "Weed was everywhere. On the bed, all over the floor." And Joe reveals the party hostess' behaviour was odd - when she wasn't updating her Twitter account, she was behaving irrationally. He explains, "One minute she's cool and down-to-earth. The next, she's totally different - indecisive, and she can't hold a conversation." The exclusive photos also include shots of Bynes posing on a mattress and applying make-up in the bathroom that features in many of her Twitpic snapshots. The actress recently told the same publication that she doesn't have a mental disorder or drink or get high, insisting, "I don't smoke pot, I smoke tobacco", but the snappers beg to differ, insisting the evidence in their photos suggests otherwise.
