Guitar legend Eric Clapton is to write his autobiography, which will be released in 2007.

Rolling Stone reports that the as-yet-untitled book will be written in collaboration with Christopher Simon Sykes, a close friend of Clapton's since the late 1960s.

The book will also be issued in audio format and its release will coincide with a retrospective box of Clapton's work.

Clapton released his new studio album, 'Back Home', earlier this year.
