Taylor Swift Regrets Putting Ex Joe Jonas 'On Blast' When She Was a Teenager

"That was too much."

Taylor Swift is answering all of Ellen DeGeneres' burning questions.

On Wednesday's episode of The Ellen DeGeneres Show, the "ME!" singer is asked a series of questions, and answers candidly when asked about the most rebellious thing she did as a teenager. 

"Probably when I like put Joe Jonas on blast on your show," Swift tells DeGeneres. "That was too much, that was too much."

"I was 18, yeah," she continues. "We laugh about it now, but that was mouthy, yeah, some teenage stuff there."

DeGeneres jokes that Swift must have "held onto" that as she doesn't remember the moment.

The incident Swift is referring to is from a 2008 episode of Ellen when Swift was promoting her album, Fearless, and shared that the songs were about "boys and love." When the daytime host asked if any of the songs were about Jonas, her boyfriend at the time, Swift revealed that they had broken up.

"There's one [song] that's about that guy, but that guy's not in my life anymore, unfortunately. That's ouch," she shared, referencing the song "Forever and Always."

"...We haven't talked since, but you know what, some day I'm gonna find someone really, really great who's right for me," she continued. "...When I look at that person, I’m not even going to remember the boy who broke up with me over the phone in 25 seconds when I was 18."

She added, "Sorry, I had to."

During the "Burning Questions" segment on Wednesday's Ellen, DeGeneres also tries to get Swift to reveal the name of her next single. "I can't tell you that. That's crazy," she exclaims, further refusing to hum any of the tune.

Swift does, however, disclose that she dropped some Easter eggs during her appearance on the show, and during her interview with DeGeneres, shoots down the rumor that she was somehow involved in Avengers: Endgame, which was released on the same day as her song, "ME!"

"We had a single coming out the same day, and I had a song called 'Endgame,' so they were like, 'Oh my God, she's gonna defeat Thanos!'" she says of the fan theory. "So, I let everyone down, again."
