The life of singer Marianne Faithfull, former wild girl of rock, is to be made into a film.

Faithfull told BBC News that she has agreed to let her life story be told as a film. It will be based on her 1994 autobiography, Faithfull.

"It won't happen right away, but we have found a director I trust who wants to make a film of the book," said Faithfull, now 62, who will release her 22nd album, Easy Come, Easy Go, next week.

She said she plans to keep a distance from the project and wants no say in which actress will portray her on screen.

"I'm not getting involved," she said. "I'll read the script when it's ready, which won't be for a long time, and then I'll leave it to the director and the actress he chooses."

Faithfull, educated in an convent in England, found fame in the 1960s as the girlfriend of Rolling Stones lead singer Mick Jagger, and emerged as an artist in her own right.

As Tears Go By, written by Jagger and Keith Richards and performed by Faithfull, was a hit on both sides of the Atlantic. A string of successful singles followed, including This Little Bird, Summer Nights, and Come and Stay with Me.

Faithfull's addiction to heroin and cocaine threw her career into a tailspin and she spent two years living on the streets of London in the 1970s.

After years of battling her addictions, she made a comeback in the 1980s, branching into acting on the stage and screen as well as making music.

In 2006, she was diagnosed with early stage breast cancer, but recovered.
