John Mayer: I Never Got Over Jennifer Aniston

John Mayer won't shut up about Jennifer Aniston.

The attention-loving singer poses shirtless on the cover of Rolling Stone magazine, and yaps about his most tabloid-friendly relationship to try to make himself relevant. The guy has albums to sell, after all.

"I've never really gotten over it," Mayer says of his very public relationship with Aniston. "It was one of the worst times of my life."

Mayer, 32, accompanied Aniston to the 2009 Oscars -- providing moral support for potentially awkward Brangelina encounters -- but he reportedly dumped her thereafter.

The couple first got together in the spring of 2008, then split and reconciled later that year.
