With new album "Red" on the way and its first single, "We Are Never Ever Getting Back Together," already a Hot 100 chart-topper, Taylor Swift made her way to the iHeartRadio Music Festival at the MGM Grand in Las Vegas on Saturday night (Sept. 22) to talk about her forthcoming music. When asked by Billboard's Jonathan Brooks about the inspiration of "We Are Never Ever Getting Back Together," Swift revealed that the song was inspired by an unwanted studio run-in.

"It's a song that just kind of happened," the 22-year-old singer told Billboard of her already ubiquitous No. 1 hit (her first on the Hot 100.) "I was in the studio, and this guy who walked in was a friend of my ex's. And he made some comment about how he heard how I was gonna get back together with my ex. And after he left I was talking to Max [Martin] and Shellback [the song's co-writers and producers] and was like, 'we are never ever getting back together!" And after that happened I just grabbed my guitar."

Wearing a flowing red dress, Swift also discussed "Red," her fourth album due out Oct. 22, and how she has used the album to aspire "to be different from what I've been, and somehow end up where I'm going. You want to provide your fans with something exciting, but you don't want them to be listening to the album going, 'I don't recognize her.' So it's somewhere in the middle. You have to find a balance."

Swift rocked the iHeartRadio fest, now in its second year, alongside P!nk, Linkin Park, Pitbull and Mary J. Blige (who brought out special guest Prince) on Saturday night. Last week, "We Are Never Ever Getting Back Together" slipped to No. 2 on the Hot 100, as Maroon 5's "One More Night" climbed to the top spot.
