Stand down Swifties, Travis Kelce has finally named his all-time favorite Taylor Swift song… and the answer may come as something of a surprise.

For many months, fans of the pop superstar have wondered which song her NFL star boyfriend holds in highest regard.

At Eras Tour shows around the world, Kelce has belted out all the classics, and has also presumably heard many secret songs behind the scenes living with Swift herself.

After her surprise performance in Nashville earlier this week, Swift’s music is back in the headlines once again, and Kelce has been quizzed on his favorite song of hers.

In an interview with Bussin with the Boys host Will Compton, Kelce took a second and then revealed a surprise selection: So High School.

It has been widely claimed in the past that some of the lyrics in the song reference Kelce and their relationship, particularly the line: ‘You know how to ball, I know Aristotle’.

Another part of the song sees Swift sing ‘are you gonna marry, kiss, or kill me’, which fans claim is a reference to a viral interview in which Kelce was asked to choose between Swift, Ariana Grande and Katy Perry.

Some Swift fans would perhaps have expected Kelce to choose ‘Karma’ as his favorite song, given the pop superstar regularly changed the lyrics to reference Kelce and her ‘guy on the Chiefs’ during her sold-out Eras Tour show.

On Thursday, meanwhile, NFL star George Kittle lifted the lid on Swift’s shock performance at a concert hosted by Kelce in Nashville on Tuesday night.

The singer sent the crowd wild with a rendition of Shake It Off as she joined Kane Brown at ‘Tight Ends and Friends’, much to the surprise of those in attendance.

Now, Kittle has opened up on Swift’s cameo and revealed that she was unsure over which song to perform before being reassured by Kelce’s pals.

Speaking to Fox News Digital, Kittle explained: ‘She was fantastic. For the venue that, I think, it was maybe 1,000 people, that was the loudest 1,000 people I’ve ever heard in my entire life. It was an incredible experience.

‘Taylor could not have been kinder, more nice, and she was like, “I think it might be fun to go sing ‘Shake It Off.'” And we were like, “It’d be amazing. Twist my arm, Taylor, please”.’
