Watch: Prince William ‘dad dancing’ to Taylor Swift at Wembley concert

As embarrassing as dad dancing can be, Prince William’s uninhibited performance at Taylor Swift’s first Wembley concert was as enthusiastic as it was vigorous.

As soon as the pop star’s hit song Shake it Off began on Friday evening UK time, the Prince of Wales was on his feet cavorting with arms and hips swaying in time to the rhythm.

In the private royal box, Prince George, 10, and Princess Charlotte, 9, also eagerly danced as they celebrated their father’s 42nd birthday.

The Royals were among 90,000 other “Swifties” – loyal fans of the singer – who attended the London stadium for Taylor's The Eras Tour.

One eagle-eyed concertgoer captured the moment Prince William and his children were lost in carefree abandon as they danced and sang the chorus “I shake it off, I shake it off”.

Within minutes, the video went viral on social media; some praised Prince William’s “impressive dad dancing”, and others were simply delighted that “Prince William is a Swiftie”.

One simply stated: “This is my favourite thing ever! I never knew I needed to see Prince William dancing to Taylor Swift!”

What followed for the three royals would have been the envy of every Swift fan.

After the concert, Taylor and Travis Kelce, her NFL footballer boyfriend, invited the trio backstage.

The post addressed to @‌KensingtonRoyal also featured emojis of a British and American flag with a pair of hands shaking.

Kensington Palace replied with a similar picture on X, formerly Twitter, adding: “Thank you @‌TaylorSwift for a great evening!”

The Princess of Wales stayed at home with Prince Louis, 6.

The Royal family had earlier even welcomed Taylor to London by posting a video of a special Changing of the Guard performance of Shake It Off. It featured the caption: “Can’t stop, won’t stop groovin’”.

Prince William has known Taylor for at least 10 years. In 2013, she encouraged him to take to the stage with her and Jon Bon Jovi to perform the hit Livin’ On A Prayer. The unlikely musical collaboration took place at the Centrepoint Gala Dinner at Kensington Palace in November that year. Footage of that clip also went viral.

Bon Jovi said, “It was all her. She literally grabbed him by the arm and ran up on stage, and they both knew the words and sang along.”

Two years ago, William revealed that he had agreed to join them on stage because he became like a “puppy” when she told him to follow her.

Taylor's Wembley gig, the first in the capital for the tour, was attended by numerous celebrities including Bridgerton star Nicola Coughlan, Queer Eye’s Jonathan Van Ness and model Cara Delevingne.

The hugely anticipated gig marks the first of three London dates on her Eras Tour. She opened the show by saying: “What better way to spend a Friday night than in the most exhilarating city in the world?”
