New Hollywood bad girl Amanda Bynes, arrested on April 6 for DUI after clipping a cop car, refused a police officer’s request to take a blood test after the Breathalyzer registered a 0.0, sources tell us. Now we’re told the former Nickelodeon child star could be “in a lot of trouble” if she is convicted. Charges are expected in the next two to three weeks, the source said, adding, “She has finally agreed to lay low, but is still refusing to go to rehab.” Her rep declined to comment.
