The Rolling Stones' latest tour is reportedly in jeopardy following a row over the size of Sir Mick Jagger's manhood.
The group's frontman is said to still be angry with his bandmate Keith Richards after he claimed in his autobiography and an interview last year that Mick had a small penis and plans for a new set of concerts have been put on hold.
A source told the Daily Mirror newspaper: "Mick read Keith's book before publication and didn't have any great problem with it.
"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."
The band were set to tour this year but it is now looking increasingly unlikely, while organisers of the 2012 London Olympics are desperately trying to get them to perform at the opening ceremony.
In his book 'Life', Keith referred to Mick as "unbearable" as well as saying his former girlfriend Marianne Faithfull had "no fun with his tiny todger".
Mick, 67, hit back at Keith, 66, describing the autobiography as "tedious".
He said: "Personally. I think it's really quite tedious raking over the past. Mostly, people only do it for the money."
