VIDEO: Keith Richards Rips Mick Jagger In New Book

Keith Richards takes a few shots -- some, literally below the belt -- at his Rolling Stones bandmate Mick Jagger in his upcoming autobiography Life, RadarOnline.com has learned.

"It was the beginning of the eighties when Mick started to become unbearable," Richards wrote in the book, adding he hasn't seen eye-to-eye with Jagger going on two decades, though they still maintain a professional relationship.

"Sometime I think, 'I miss my friend,'" Richards, a pal of Jagger's since early childhood, wrote in the memoir. "I wonder, 'Where did he go?'"

Richards implied in the book that Jagger's got a big ego to make up for a small penis -- not so, says Jagger’s ex, Jerry Hall.

"Mick is very well endowed,  and I should know because I was with him 23 years," Hall told the BBC. "Keith is just jealous you know."

Life hits bookstores October 26.
