Shortly after having to deny he snorted his own father�s ashes, Rolling Stone Keith Richards is now mourning the death of his mother.

Doris Richards died peacefully last night aged 91, with Keith by her side.

The rocker had been keeping a bedside vigil by his mother as she battled cancer at a clinic in Harley Street, London, according to The Sun.

Keith had to explain earlier this month his claims he had snorted the ashes of his dad Bert - who died five years ago aged 84 - along with a sprinkling of cocaine was in fact a joke.
