Much to DeGeneres' dismay, Swift vehemently denies she ever dated Zac Efron -- despite the adorable duet they performed together during her last appearance on the show. "There's nothing really about Zac on the CD . . . because we didn't date," the singer said.
In order to try and determine who her new song, "We Are Never Ever Getting Back Together," is about, DeGeneres decided to show a slideshow of Swift's rumored exes. She then asked Swift to ring a bell for three pictures, so the audience could narrow down who it is about.
"But I don't want to! I don't want to!" Swift shouted. "Because they'll send me angry emails and I don't want to get them!"
"Stop it, stop it, stop!" Swift screamed. "This makes me feel so bad about myself. Every time I come up here you put a different dude up on the screen. It just makes me really question what I stand for as a human being. There's never been two guys on the screen two visits in a row. It's sad."
