It all went down when T-Swift stopped by The Tonight Show on Tuesday, February 17. Jimmy started things off by telling her he had a confession to tell her...ew!
"I'm kind of a little upset," he told Taylor. "I'm a little upset because every time I see you dancing at events, and for a while, that was our thing." She reminded the host that their public dancing happened "a long time ago," adding, "We used to go all out. I'm sorry."
"I forgot about that being our exclusive thing," she added. "We were famous Jumbotron dancers," Jimmy responded.
They reminisced about attending sporting events in New York, and after contacting various arenas, Jimmy recovered the footage and shared it with viewers.
In typical Jimmy fashion, It's pretty much the funniest thing ever. Watch below.
