Shocking New Michael Jackson Drug Revelations

Michael Jackson insider Dr. Susan Etok recalls the moment when the King of Pop allegedly asked her for the drug Diprivan -- and weighs in on Mark Lester's claim that he may be the biological father of Paris in part two of her incredible ET interview!

"Alarm bells went off in my head and I knew I needed to get out of there right away," says the surprise witness about when Jackson allegedly asked her for Diprivan -- and reportedly knew the proper dosage he needed. "When somebody has an addiction all they care about is getting their next fix."

On Friday morning, former 'Oliver!' child actor Mark Lester, who was good friends with Jackson and godfather to his children, said on the "Today" show that he believed he was the biological father of Michael's daughter Paris after donating sperm.
