  • Prince William attended The Eras Tour with Prince George and Princess Charlotte in London.

  • The British royals posed for photos with Swift and her boyfriend, Travis Kelce.

  • Footage showed William, who celebrated his 42nd birthday, dancing to "Shake It Off."

The Prince of Wales is a certified Swiftie.

William rang in his 42nd birthday on Friday at Taylor Swift's concert in London with his two eldest children, 10-year-old Prince George and 9-year-old Princess Charlotte.

The British royals were among the massive crowd that arrived at Wembley Stadium, where Swift, 34, kicked off the European leg of The Eras Tour.

The trio commemorated the night by posing for a selfie with Swift, whom they thanked in an Instagram post on the Prince and Princess of Wales' official account.

"Thank you @taylorswift for a great evening!" the caption read on Saturday.

Swift also shared an Instagram photo on Saturday featuring royal family members and her boyfriend, Travis Kelce. The group was all smiles in the picture.

"Happy Bday M8! London shows are off to a splendid start," Swift's caption read.

William's attendance at The Eras Tour didn't go unnoticed by Swifties, including one who shared a TikTok video of him dancing to "Shake It Off."

Neither Catherine, Princess of Wales, nor six-year-old Prince Louis appeared at the concert. Kate, 42, made her first public appearance since her cancer diagnosis earlier this month at the Trooping the Colour Parade.

Kate shared details about her recovery in an Instagram post one day before the parade, saying she's making "good progress" with her chemotherapy treatment.

"I'm looking forward to attending The King's Birthday Parade this weekend with my family and hope to join a few public engagements over the summer, but equally knowing I am not out of the woods yet," the caption read. "I am learning how to be patient, especially with uncertainty. Taking each day as it comes, listening to my body, and allowing myself to take this much needed time to heal."

Representatives for Kensington Palace, Swift, and Kelce did not immediately respond to a request for comment from Business Insider.
