John Mayer has long been known for being something of a ladies man - and he's not shy when it comes to kissing and telling (lest you forget, he infamously referred to Jessica Simpson as "sexual napalm"). The target of his latest admission? Taylor Swift - but not in the way you might think.

Mayer and Swift were rumored to have dated briefly, and Swift's song, "Dear John," from her 2010 album Speak Now, is said to have been written about Mayer. But Swift has never admitted it outright.

In a new interview with Rolling Stone - on newsstands Friday - Mayer, 34, says he was "humiliated" by the song.

"It made me feel terrible because I didn't deserve it," he says. "I'm pretty good at taking accountability now, and I never did anything to deserve that. It was a really lousy thing for her to do."

In "Dear John," Swift, now 22, sings, ""Dear John, I see it all, now it was wrong / Don't you think 19 is too young to be played by your dark twisted games, when I loved you so?"

Listen to "Dear John":

Mayer went on: "I was really caught off-guard, and it really humiliated me at a time when I'd already been dressed down. I mean, how would you feel if, at the lowest you've ever been, someone kicked you even lower?" He adds, "I will say as a songwriter that I think it's kind of cheap songwriting... I know she's the biggest thing in the world, and I'm not trying to sink anybody's ship, but I think it's abusing your talent to rub your hands together and go, 'Wait till he gets a load of this!' That's bulls***."
