Diddy's twin daughters were surrounded by drug use and even covered in a mysterious white powder, according to a lawsuit against their mom Kim Porter.
Dawn Drago says she worked for Diddy's ex as a nanny from 2011-12, when she claims Kim chain-smoked pot in the house while the girls were home.
Drago alleges she found cocaine as well, and on one occasion was driving the kids to school and noticed they were covered "in a white powdery substance."
Drago claims the kids got into "a bag containing the powder, along with clear capsules, filled with another powdery substance in a bag in the back seat."
Drago says she confronted Porter, who said the bag contained "medicine."
The nanny also claims she was verbally and violently abused before eventually being fired last year, which is what ties into her lawsuit against Porter.
Drago says the constant marijuana smell was choking and she dared to complain when she couldn't take it, so she was dismissed by Kim Porter.
She is seeking unspecified damages; Diddy and Kim were together for years but never married. He has three other children from previous relationships.
He is NOT dating Kate Upton now, however. He shot down that rumor.
