Taylor Swift’s ‘Shake It Off’ played by Buckingham Palace royal guards before her London show

They’re shaking it off.

The notoriously stoic royal guards outside of Buckingham Palace appear to be Swifties.

The royal family shared a video on Instagram of the royal guard playing Taylor Swift’s hit song “Shake It Off” in front of Buckingham Palace on Friday.

This comes ahead of the pop star’s London concerts, kicking off this weekend.

In the video – which is accompanied by the caption “Can’t stop, won’t stop groovin’” –  the royal guards are in a half-circle formation, playing flutes and trumpets, led by a conductor with a sword and a guard hat.

In the video, Swift’s song “Shake It Off,” from her 2014 album “1989” can be heard playing. Other members of the royal guard are in the background.

Swift will perform at London’s Wembley Stadium starting Friday.

Earlier this week, she performed in Cardiff, Wales. “Next up: our weekend at Wembley!!” Swift wrote on Instagram. “See you tomorrow London!

The Grammy winner – whose private jet has become targeted by climate activists – previously lived in the city, with her British ex-boyfriend, Joe Alwyn, 33, who she dated for six years from 2016 to 2023.

Their relationship was more low-key and private than her relationship with past famous exes, such as Tom Hiddleston, 43.

Swift has referenced the city in several songs, including, “So Long, London” and “London Boy.”

On Swift’s most recent album,, “The Tortured Poets Department,” the pop star seemingly admits that she was more emotionally wounded from her breakup with Alwyn than it seemed at the time.

In her song “I Can Do It With a Broken Heart,” the 13th track on the album, Swift says that she was only pretending to be happy following their split, which took place just before she started her Eras tour last year.

The “Conversations with Friends” actor recently broke his silence about his split from Swift, who has since moved on to a high-profile romance with NFL player Travis Kelce.

“I would hope that anyone and everyone can empathise and understand the difficulties that come with the end of a long, loving, fully committed relationship of over six and a half years,” Alwyn told the Times in an interview published Saturday, making his first official comments following their separation.

“That is a hard thing to navigate.”

“What is unusual and abnormal in this situation is that, one week later,” he added, “it’s suddenly in the public domain and the outside world is able to weigh in.”
