Taylor Swift: John Mayer is ‘presumptuous’ to think ‘Dear John’ is about him

Taylor Swift has made it clear she writes about her romances. In March 2010, she reportedly had a brief fling with John Mayer after the two collaborated on a song together. Then seven months later, she released her album, Speak Now, which included the song "Dear John" about an older guy who broke her heart. Everyone assumed it was about Mayer — even he did, telling Rolling Stone earlier this year that it was "a really lousy thing for her to do." However, Swift says not so fast.

"How presumptuous!" she tells Glamour in an interview to promote her new album, Red, out October 22. "I never disclose who my songs are about." When ABC's Cynthia McFadden, who interviewed Swift for the magazine, attempts to read Mayer's quotes, the country singer cuts her short. "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. I put a high priority on staying happy, and I know what I can't handle. It's not that I'm this egomaniac and I don't want to hear anything negative, because I do keep myself in check. But I've never developed that thick a skin. So I just kind of live a life, and I let all the gossip live somewhere else. If you go too far down the rabbit hole of what people think about you, it can change everything about who you are."

Swift, 22, also didn't want to dish any details about her newest romance with 18-year-old high school student Conor Kennedy, whom she spent most of her summer with in Massachusetts (she even bought the house across the street from his family's home). "I don't talk about my personal life in great detail," she says. "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."

But Swift did open up a little about the L-word in another interview with the U.K. edition of Marie Claire, in which she says she does still believe in it "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?' But then, when you make eye contact with someone across the room and it clicks and, bam, you're there. In love again."

Her songs may make it sound like Swift falls in love with every guy she meets, but she clarifies that although that seems like the case, she only likes someone "if it's the right person." Of course, some guys turn into Mr. Wrong (cough, John Mayer, cough), and then she gets revenge … in song. "Music is absolutely everything that I am and everything that I stand for," she explains, careful to not name names. "It's not my fault if someone gets into a relationship with me and then cheats and I write a song about it."

There was another relationship that Swift was happy to talk about: the one with her famous BFFs Selena Gomez and Emma Stone. "They are so important in my life right now," she tells Glamour. "I'm the kind of girl who needs to tell her friends everything. I've developed this really close-knit group of girls … I met Emma when I was 17, and I met Selena when I was 18. So they've experienced all of this with me, and they've also experienced their own amazing success, and somehow through all of it, we've stayed close."

Of course, she has some non-Hollywood friends, too, including two of her female bandmates. When asked whether she's ever worried that some people may try to align themselves with her only because of her fame and her money, Swift acknowledges that she knows it's a possibility … but it could be worse. "I think you can tell who's a good person to be around, who makes you laugh, who's fun, whom you can trust," she says. "And, yes, you're going to get burned a few times, but I'd really rather get burned a few times than sit alone in that house with the curtains drawn. So God forbid this person you're hanging out with gets a bit of validation out of the fact you're famous. Is that the worst-case scenario? You know, it doesn't seem that bad."
