Taylor Swift talks about her song, "Dear John"

Taylor Swift may still be hurting from her breakup with John Mayer.

In the November issue of Glamour magazine, Swift was asked about her 2010 hit "Dear John" and what she thinks about Mayer's recent comments to Rolling Stone about the track, rumored to be about him.

"How presumptuous!" Swift, 22, told Glamour. "I never disclose who my songs are about."

Mayer told Rolling Stone in June that Swift's song "humiliated" him. "It made me feel terrible," he said, "Because I didn't deserve it." The 34-year-old singer briefly dated Swift in 2009. "["Dear John" is] cheap songwriting," he added. "It's abusing your talent to rub your hands together and go, 'Wait til he gets a load of this!' That's bulls--t."

But Swift told Glamour she didn't want to know what exactly he said to the magazine about the song. "I know it wasn't good, so I don't want to know," she explained. "I put a high priority on staying happy, and I know what I can't handle."
