Keith Richards’ jabs at Mick Jagger in his new memoir Life may hamper the Rolling Stones’ 2011 tour plans, according to the newspaper The Daily Mirror.

“Mick read Keith’s book before publication and didn’t have any great problem with it,” an article in the paper states. “It was the fact that it was all dredged up in the interview afterwards that really upset him. Many believe this is the real reason why talks in relation to the tour have broken down.” As the article states, Richards describes Jagger as “unbearable to work with” and goes on to say that his former girlfriend Marianne Faithfull had “no fun with his tiny todger.”

Fans and industry insiders alike expected the Rolling Stones to tour in 2011 and even play some of the major US festivals. As of press time the Stones have no confirmed plans, though Jagger will perform at the Grammys for the first time in his storied career this coming Sunday. The singer will pay tribute to the late soul legend Solomon Burke.
