Prince William Dances Like No One's Watching to Taylor Swift's 'Shake It Off' at Eras Tour in London

Prince William can't stop and won't stop grooving!

The royal, 42, was spotted dancing along to Taylor Swift's song "Shake It Off" during the first night of her Eras Tour stop in London on Friday, June 21, as seen in fan-captured footage from the concert.

In the clip, William is seen letting loose in the stands and dancing along to Swift's tune from her 1989 album while wearing a blue ensemble.

Princess Charlotte, meanwhile, could be seen to her father's left side, swaying along to the beat as Swift, 34, sang the tune onstage.

During Swift's first Eras Tour stop in the U.K., she posed for a selfie with Prince William, Prince George and Princess Charlotte, as seen in a photograph shared on the Prince and Princess of Wales' official Instagram account.

In the image, Swift stands alongside the three royals while holding up a phone to snap a photograph of the group. "Thank you @taylorswift for a great evening! #LondonTSTheErastour," the post's caption read.

In a photo posted on her own Instagram account, Swift shared a snapshot of herself posing with Prince William, Prince George, 10, and Princess Charlotte, 9 — as well as her boyfriend, Travis Kelce. (The photo is the first time she and Kelce, 34, have appeared in a social media post together.)

"Happy Bday M8! London shows are off to a splendid start 🇬🇧🇺🇸🤝," the singer captioned her post, referencing Prince William's birthday.

While William, George and Charlotte enjoyed Swift's performance, Prince Louis, 6, likely stayed home with mom Kate Middleton, who has remained largely out of the public eye in recent months as she continues her cancer treatment.

She recently made a special appearance on June 15 at Trooping the Colour, the annual celebration of King Charles' birthday, marking her first public outing with the royals since Christmas.

Swift was previously welcomed to London by the royal guard earlier on June 21, when the band played "Shake It Off" in front of Buckingham Palace.

"Can’t stop, won’t stop groovin’🫡🥁🎺," the royal family captioned a video of the performance on social media.
