[Taylor Swift Kicks Off London Tour Stop with Royal Selfie] Taylor Swift and Travis Kelce might be the closest thing to royalty that Americans have, so a selfie with actual British royalty feels fitting.

The pop superstar and her NFL-playing boyfriend posed for a selfie on Friday night with Prince William and two of his three children, Prince George and Princess Charlotte during night one of her Eras Tour stop in London.

The official Prince and Princess of Wales Instagram account first shared a photo of the five standing together backstage, captioning the post, “Thank you @taylorswift for a great evening! #LondonTSTheErastour.” Swift then shared it to her own account and wished Prince William a happy birthday.

Swift can be seen wearing one of her many concert outfits — the long bedazzled blazer she wears while singing “The Man.” The royals were all smiles as they stood next to Swift and Kelce, the latter wearing a Team USA Olympics hat. She captioned the photo, “Happy Bday M8! London shows are off to a splendid start 🇬🇧🇺🇸🤝.”

Kate Middleton, Princess of Wales, and their youngest child, Prince Louis, were both absent from the concert and selfie, as Kate continues to undergo cancer treatment. The Princess of Wales made her first public appearance in six months on June 15 to attend Trooping the Colour to honor King Charles’ birthday. The royals have mostly kept Kate’s treatment private, but assured the public that she is “making good progress.”

Taylor Swift kicked off her three-night Eras Tour stop at Wembley Stadium as part of the international leg of her multibillion-dollar Eras Tour. She rocked the London stadium on June 21 with openers Paramore and Mete, to a crowd of more than 88,000 people. The stadium was packed with fans and celebrities alike — including Cara Delevingne, Nicola Coughlan, Jonathan Van Ness, Jason Kelce and his wife Kylie Kelce, and Salma Hayek.
