Taylor Swift's ex-boyfriend John Mayer feels humiliated over the song "Dear John."

Taylor never confirmed that the song was about Mayer, but he thinks it is, particularly because of the title.

In a new interview, Taylor was angry to hear that the he thought the song was about him:

"How presumptuous! I never disclose who my songs are about."

Taylor didn't want to hear any more about the John thing because she wanted to avoid drama.

Meanwhile, John Mayer is still dating Katy Perry and Taylor Swift is dating Conor Kennedy.
