If you need some extra time to process that, we'll wait.
Swift has been dating Joe Alwyn since September 2016, and Joe Jonas is now engaged to Game of Thrones star Sophie Turner. Taylor is now in a relationship with actor Joe Alwyn, though the pair haven't announced wedding plans just yet.
Speaking in an interview with Ellen Degeneres during a recent appearance on The Ellen Show, Swift chose to open up about the Endgame rumor after being asked about the most ridiculous things fans believed about her.
She told Ellen in her new interview: "Probably when I like put Joe Jonas on blast on your show". That was too much.
American pop sensation Taylor Swift has been known to be throwing shade at her former lovers from time to time in her songs but it looks like she has some regret over doing it to a certain someone who is now married. But to be fair, Swift admits she didn't exactly handle the split well herself. 'We laugh about it now, but that was mouthy, yeah, some teenage stuff there'.
Indeed there was but it was less of a tune about "love" than it was about the boy who broke her heart (Jonas) - and over the shortest phone call ever, no less, as Swift revealed on the show.
"For those who have expressed concern over the "27 second" phone call, I called to discuss feelings with the other person", Jonas wrote.
If your memory is lost on the infamous moment, the "Delicate" songbird is referring to the time she appeared on Ellen back in 2008 as she was coming off the success of her sophomore album, Fearless.
