SEAN 'Diddy' Combs' twin daughters were allegedly sent to school "covered in cocaine" by their mother.

Kim Porter is accused of using drugs around the former couple's six-year-old girls in a new lawsuit, according to TMZ.

Former family nanny Dawn Drago claims she worked for Porter from 2011 to 2012 and during that time witnessed her using drugs while the children were at home.

In filings obtained by the website Drago alleges she noticed the girls were covered "in a white powdery substance" when she was driving them to school.

She claims the children had found "a bag containing the powder, along with clear capsules, filled with another powdery substance in a bag in the back seat".

Upon confronting Porter she was told the bag contained "medicine".

Drago also accuses Porter of "chain-smoking pot" in the house with the girls home.

The plaintiff was fired in 2012.

She claims Porter "verbally and violently abused her" during her tenure and alleges was wrongfully terminated after she complained of a strong stench of marijuana.

She is seeking unspecified damages in the case.

Spokespersons for Combs and Porter have not responded to requests for comment.

The couple dated for several years before their split in 2007.

In addition to the twin girls they also share a son, born in 1998.
