Keith Richards has warned Amy Winehouse to stay away from drugs.

The Rolling Stones rocker - who has previously battled a heroin addiction - says the troubled 'Rehab' singer needs to kick her dangerous habit before it 's too late.

The 64-year-old guitarist, who once infamously joked he had snorted his father's ashes, said: "She should get her act together."

The band's frontman Mick Jagger - who was briefly jailed in 1967 for possessing drugs - has also advised young stars not to follow in the Stones' notorious footsteps.

Speaking at the Berlin premiere of Rolling Stones documentary 'Shine a Light', Mick said: "When we were experimenting with drugs, little was known about the effects."

"In our time there were no rehab centers. Anyway I did not know about them."

Mick, 64, has previously expressed concern for Amy's wellbeing saying: "I'm worried she might die if she goes down the road she has taken."
