Lynn's statement comes on the same day that Bynes' lawyer shot down reports the actress suffers from schizophrenia. "There has been much speculation about Amanda's medical condition," attorney Tamar Arminak said earlier today. "She has remained silent because she believed it was best to keep her mental health diagnosis private. However, she asked me to dispel certain rumors. For the record, Amanda does not have schizophrenia, nor has she ever been diagnosed with it."

"Amanda currently is on zero medication," Arminak went on. "She's devoted to living her life as healthy as possible. She's never had a history of abusing alcohol or hard drugs, and she's proud to say she's been marijuana-free for the past nine months."

Bynes is currently under the care of her mother Lynn and father, Rick, after being hospitalized in May of last year. The family recently celebrated Bynes' 28th birthday with a trip to Cabo San Lucas, Mexico.
