Bruce Springsteen is reportedly at work on an autobiography that could earn the rocker $10 million. The 60-year-old rocker is said to be chipping away at a manuscript that book publishers would love to get their hands on.

"It could be the biggest rock music autobiography of all time," a major publishing insider told the New York Post. "He could get $9 million to $10 million for the world rights."

Through the years there have been a number of books written about Springsteen, including officially-sanctioned bios penned by his unofficial historian, Dave Marsh. There's no word on whether Marsh -- who is married to Springsteen's co-manager Barbara Carr -- will be involved in the project.

The anonymous source claims, "Springsteen is a better writer than Marsh." That opinion aside, Springsteen is said to be interested in hiring a researcher to work with him on the project.

Insiders tell the paper that a bidding war could easily surpass the $8 million advance Rolling Stones guitarist Keith Richards landed from Little Brown for his memoir, which was twice the $4 million Broadway Books ponied up for Eric Clapton's autobiography.
