Taylor Swift Says It's "Presumptuous" For John Mayer To Assume That She Wrote "Dear John" About Him

Taylor Swift covers the November issue of Glamour Magazine, and the 22-year-old singer/songwriter opens up about some of the tunes she's penned about her famous exes over the years.

Taylor's 2010 hit "Dear John" is rumored to be about John Mayer, whom she dated briefly in 2009, and he recently told Rolling Stone, "It made me feel terrible because I didn't deserve it. ["Dear John" is] cheap songwriting. It's abusing your talent to rub your hands together and go, 'Wait til he gets a load of this!' That's bullsh*t."

So what does T. Swizzle have to say about his remarks? "No! I don’t want to know, I don’t want to know. I know it wasn't good, so I don't want to know," she said. "I put a high priority on staying happy, and I know what I can't handle." But what about the fact that he assumes the song is about their relationship? "How presumptuous!" she exclaimed. "I never disclose who my songs are about."

Swift has been dating Conor Kennedy for the past two months, but she wouldn't reveal much about their romance either. "I don't talk about my personal life in great detail," she said. "I write about it in my songs, and I feel like you can share enough about your life in your music to let people know what you're going through." Given her track record, it sounds like we'll be hearing all about this latest one in a few months...

Taylor also covers the new issue of Marie Claire UK, and she continues to babble about love and finding Mr. Right. "[I believe in love] even after it explodes into a million pieces and burns down and you're standing in a pile of the ash of what it once was thinking, 'Why did I have to meet this person, why did this have to happen?'" she says. "But then, when you make eye contact with someone across the room and it clicks and, bam, you're there. In love again."

So what does she say about her tell-all tunes? "Well, it's not like it's in fine print," she tells the magazine. "It's not my fault if someone gets into a relationship with me and then cheats and I write a song about it."
