John Mayer has revealed that he fears his obsession with Twitter.com cost him his relationship with actress Jennifer Aniston.

The 32-year-old lothario dated America’s sweetheart on and off between 2008- 2009, but Aniston, 40, found the rocker’s love of blogging, social networking, and modern technology a “courting distraction.”

“One of the most significant differences between us was that I was tweeting. There was a rumor I was dumped because I was tweeting too much. That wasn’t it,” John dishes in the March issue of Playboy. “The brunt of her success came before TMZ and Twitter. I think she’s still hoping it goes back to 1998. She saw my involvement in technology as courting distraction, and I always said, ‘These are the new rules,’” he added.

John — who contends that he still loves Jennifer — also has fond memories of former flame Jessica Simpson:

“Sexually it was crazy. That’s all I’ll say. It was like napalm, sexual napalm….” the star smirked. “That girl, for me, is a drug,” Mayer drooled. “And drugs aren’t good for you if you do lots of them. Yeah, that girl is like crack cocaine to me.”
