The Prince of Wales has thanked Taylor Swift for a “great concert” as he shared a photo of the pop superstar taking a selfie with him and his children George and Charlotte.
Watching the US singer perform at Wembley Stadium, the future king was also spotted shaking his arms to Shake It Off as he celebrated his 42nd birthday.
“Thank you Taylor Swift for a great evening,” Prince William wrote on Instagram.
Swift posted her selfie with William, George and Charlotte alongside her boyfriend, NFL star Travis Kelce.
“Happy Bday M8,” Swift wrote on Instagram. “London shows are off to a splendid start.”
William’s cousin Zara Tindall and her husband Mike Tindall were among the star-studded crowd, which reportedly included Bridgerton star Nicola Coughlan and model Cara Delevingne.
Labour leader Sir Keir Starmer was also present as he took time off from the campaign trail to attend the first night of the London leg of Swift’s record-breaking Eras tour.
