Sir Elton John has criticised Keith Richards for publicly claiming Sir Mick Jagger has a small penis and insists his working relationship with his songwriting partner Bernie Taupin would be irrevocably damaged if he said that about him.
Keith claimed Mick's ex-girlfriend Marianne Faithfull had "no fun with his tiny todger" in his autobiography 'Life' and further ridiculed the 'Satisfaction' singer in a subsequent interview.
Speaking about the book, Elton, 63, told Rolling Stone magazine: "I was a bit put off by hearing about Mick's penis. I'm a big Mick Jagger fan.
"If I said that Bernie Taupin was a miserable **** and had a small penis, he'd probably never talk to me again. It's like, 'Why do that?' especially with someone you're in a working relationship with."
Mick is now reportedly so angry with his bandmate and long-time friend the rift is affecting plans for a Rolling Stones tour.
The 67-year-old singer's ego took a further knock when Marianne - who dated him from 1966 to 1970 - didn't do much to dispel the rumours, saying Keith's comments are "nearly" true.
