Joe Perry isn’t so sure that Steven Tyler hasn’t read his autobiography, Rocks: My Life in and out of Aerosmith. Tyler made that claim last week when TMZ cameras caught up with him in Nashville.

Perry says, “As far as I know, Steven has read the book, from what I have gathered. Actually he texted me and said he read the first four chapters and really liked it. He said the packaging was very good as well as the pictures and art and all that stuff. Those are the kinds of things he would notice. That’s the best information I can give you.”

Tyler said he’d refused to read the book because he has to “go onstage with him next year. I wanna love the son of a bitch.” He added that Perry hasn’t read his book, Does the Noise in My Head Bother You?
