Prince William celebrated his 42nd birthday with his kids at the gig at Wembley Stadium, where The Prince of Wales was spotted showing off his amazing dance moves at Taylor Swift's first The Eras Tour concert last night.

The future king attended the event with Prince George, 10, and Princess Charlotte, 9.

The videos of the Prince of Wales dancing in the stadium filled with crowds screaming Swifties have been shared on social media.

William can be seen on the patio shaking his arms to the music while wearing a jacket and button-down shirt.

The video starts with Swift performing Shake It Off from a distance on stage before turning to William swaying his arms and smiling as he danced.

Princess Charlotte may be seen imitating her father and the other kids in attendance at Wembley Stadium.

Zara Tindall, William's cousin, and her husband Mike Tindall also attended the event.

The official X account for Taylor Swift's 'The Eras Tour' shared a video of Prince William dancing and said, "Prince William vibing and dancing along to "Shake It Off" at Night 1 of Taylor Swift's tour in London!"

Earlier, Swift's Shake It Off was played by Buckingham Palace's military band during the changing of the guards' ceremony.
