Taylor Swift delighted Zurich with a mashup of her Joe Jonas breakup track Last Kiss during her Tuesday evening concert.

The songstress, 34, performed a mix of Last Kiss with Sad Beautiful Tragic during her concert at Switzerland.

Swift wrote the song following her months-long romance with the Jonas Brothers musician.

In video posted online of the performance, Taylor – who is now dating Travis Kelce – sits at the piano as she belts out the mashup with feeling.

‘Taylor Swift performing a mashup of “Last Kiss” and “Sad Beautiful Tragic….. This is so heartbreaking… BRB crying,’ one fan tweeted in response to the video.

‘Whoa, that was insane! Taylor just blew the roof off with that Last Kiss/Sad Beautiful Tragic mashup. Her vocals are so powerful and emotive, it gives me chills every time,’ another tweeted.

Taylor and Jonas were just teenagers when they dated from July to October 2008.

She went on to pen several break-up songs thought to be about him, including Forever and Always, Mr Perfectly Fine, Better Than Revenge and Last Kiss. They have long since made amends, however.

Obviously, both have moved on since their teenage romance – Taylor is now dating football player Travis Kelce while Joe went on to marry Sophie Turner in 2019.

However, Joe and Sophie have now split up – they filed for divorce from one another last year.

The Mean songstress has since formed a close friendship with Sophie after the Game Of Thrones actress broke up with Joe.

Shortly after breaking up with Joe in 2008, Taylor opened up on The Ellen DeGeneres Show and revealed that Joe had broken up with her over a 25-second phone call. ‘Some day, I’m gonna find somebody really, really, really great, who’s right for me,’ the singer stated.

‘When I find that person that is right for me, he’ll be wonderful and when I look at that person, I’m not even gonna be able to remember the boy who broke up with me over the phone in 25 seconds when I was 18,’ she added.
