Hollywood’s newest troubled starlet, Amanda Bynes, is telling friends her Breathalyzer test was negative on the night of her DUI arrest. A source close to the former Nickelodeon actress, who was busted earlier this month after clipping a cop car, tells us: “She is saying she blew a 0.0 on the night she was arrested for DUI. Amanda is hopeful that she won’t be charged. But the bigger concern to her aides is her state of mind and her health. She hasn’t been herself in almost two years, and is clearly struggling. She has been told not to go out to clubs and to lay low. She is truly a little girl lost right now.” Despite the warnings, Bynes has continued to hit the party circuit. Her rep could not be reached last night.
