On the Wednesday, May 15 episode of The Ellen DeGeneres Show, Taylor, 29, participated in a game of "Burning Questions" where Ellen, 61, asked the star,
"What is the most rebellious thing you did as a teenager?"
"Probably when I like put Joe Jonas on blast on your show," the singer said of the interview in 2008. "That was too much, that was too much."
"I was 18, yeah," Taylor added. "We laugh about it now, but that was mouthy, yeah, some teenage stuff there." The host then joked that the incident must have "held onto her" as she "doesn't remember that at all."
As fans know, Taylor and Joe, 29, dated briefly from July to October 2008 until the Jonas Brother broke up with the 10-time Grammy winner.
Before their split became public, the star called out Joe on the comedian's show after Ellen asked Taylor about their relationship and whether or not any of the songs on her (then) new album Fearless were about him.

"There's one song that's about that guy, but that guy's not in my life anymore, unfortunately. That's ouch," she said at the time, referring to her famous track "Forever & Always."
"We haven't talked since, but you know what, someday I'm going to 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."
