Chaka Khan has gone into rehab, saying she is addicted to the same potent drug that led to the death of her friend Prince.

Khan said she was taking action to save her life.

Yvonne Stevens, the Grammy award winner's sister, has also entered the rehabilitation and aftercare programme.

In a statement on Sunday, the US singer said: "The tragic death of Prince has had us both rethinking and reevaluating our lives and priorities.

"We knew it was time to take action to save our lives. My sister and I would like to thank everyone for their support, love and prayers."


Khan had a big hit covering Prince's I Feel For You in 1984 and the two were good friends.

The 63-year-old star apologised to fans that she would now miss appearances over the summer but said it was "vital that I put my health and well-being first".

Prince died in April after overdosing on fentanyl, a potent opioid painkiller that can be up to 100 times stronger than morphine and 50 times that of heroin.
