Lindsay vs Dr. Drew!

VH1 addiction "expert" DR. DREW PINSKY has been diagnosing LINDSAY LOHAN from afar for months now, and she's had enough.

Lindsay told some website called GossipCop.com, quote, "He's a quack and a sell-out...Please tell him to stop!"

Most recently, Drew said, "If she were my daughter, I would pack her car full with illegal substances, send her on her way, call the police, and make sure she was arrested. I would make sure she was not allowed to get out of jail. I would then go to the judge and make sure she was ordered to a minimum of a three year sobriety program."
