Taylor Swift appeared to take a swipe at ex-boyfriend Calvin Harris on the latest show of her phenomenal Eras tour.

The Fortnights singer is currently doing the first UK leg of her international tour, and on Friday performed at Liverpool’s Anfield Stadium.

As has become tradition throughout her tour – where she’s celebrating the album’s she’s released to date – Taylor dropped two surprise songs unique to the gig.

The first was a mash-up of Gold Rush from her album Evermore, and Calvin Harris track This Is What You Came For.

Taylor co-wrote the track while she was dating the DJ – real name Adam Wiles – back in 2016, but it was later given to Rihanna.

Officially, Taylor isn’t credited on the song, with the singer opting to use the pseudonym Nils Sjöberg instead.

Before singing the song in Liverpool, she told the audience: “Every single time I have an acoustic set, I’m always trying to think of things you might want to hear — maybe things that might be a little bit unexpected.

“Let’s see how we did tonight.”

Her involvement on This Is What You Came For was only confirmed after her split with Harris in June 2016, with her rep confirming Taylor and Nils Sjöberg were one and the same.

Before that point, Harris had told Ryan Seacrest on his US radio show he would never work with Taylor, which reportedly caused upset given the smash hit the song became.

This sparked off a huge feud between the two after their split, with Harris later going off on a rant on Twitter (now X), accusing Taylor’s team of “trying to tear him down”.

He wrote: “I figure if you’re happy in your new relationship you should focus on that instead of trying to tear your ex bf down for something to do.

“Hurtful to me at this point that her and her team would go so far out of their way to try and make ME look bad at this stage though.”

“I wrote the music, produced the song, arranged it and cut the vocals though,” he added.

“And initially she wanted it kept secret, hence the pseudonym. And she sings on a little bit of it too. Amazing lyric writer and she smashed it as usual.”

Harris later rescinded his statement and said he was “blessed to work with her”, doubling down on the sentiment in an interview with GQ in 2017.

During the chat, he said he “snapped” and was “protecting what he sees as his one talent in the world being belittled”.

So fans were delighted at hearing her perform the song.

“Taylor Swift deciding to sing (for the first time ever!) This is What You Came For while in the UK, aka the song she co-wrote with Calvin Harris, is UNHINGED, I love her,” one said on X.

“Taylor Swift sings Calvin Harris This Is What You Came For in Liverpool – The best surprise songs of the tour last night in my opinion,” added a second.

Taylor’s Eras Tour – which started in March 2023 – will finish at the end of 2024.

The singer confirmed the news on stage, marking her 100th performance of the staggering three-hour show.

“This is the very first time I’ve ever acknowledged to myself and admitted that this tour is going to end in December,” she told the audience.

“This tour has really become my entire life, it’s taken over everything, like I think I once had hobbies.

“All I do when I’m not on stage is sit at home and try to think of clever acoustic song mashups and think about what you might want to hear.”
