Prince William showcased his royal dad dance moves to celebrate his 42nd birthday at Taylor Swift's concert.

The AQCANPrince of Wales let loose to the pop superstar's 2014 song "Shake It Off" at night one of Swift's run of shows at Wembley Stadium in London on Friday.

In a suite to the right side of the stage, Swifties appeared to capture the Prince of Wales shimmying to the chorus of “Shake It Off" in videos shared by multiple fan accounts and British news outlet The Sun. Users on X sounded off about the future king's dance moves during the concert.

"I am sorry but prince william dancing to shake it off has me wheeeeeezing," one user wrote, while another said, "I cannot stop watching the video of Prince William dancing to shake it off he said this is my SONG."

While Prince William celebrated with his children in the suite, Taylor Swift's boyfriend Travis Kelce and his brother, ex-Philadelphia Eagles center Jason Kelce and his wife Kylie Kelce also attended the concert. Nicola Coughlan, who is Netflix royalty in her own right as the star of the streaming platform's hit "Bridgerton," also attended.

On Saturday morning, the pop superstar posted an Instagram photo with Kelce alongside Prince William and his two eldest children, Prince George, 10, and Princess Charlotte, 9.

"Happy Bday M8!

The snap also included her first post with Travis Kelce, the Kansas City Chiefs tight end and three-time Super Bowl champion.

Prince William and Princess Kate's official Instagram account @princeandprincessofwales also posted a photo featuring a behind the scenes of the "London Boy" singer's selfie, captioning the post "Thank you @taylorswift for a great evening! #LondonTSTheErastour."

That photo featured a quartet of Swift and the three Royal Family members without Kelce. Princess Kate, who did not appear at the concert, is currently battling cancer but recently returned to public life riding in a carriage with her three children, for Trooping the Colour on June 8 last Saturday to celebrate her father-in-law King Charles III's birthday.
