What did you think of Prince William and Taylor Swift’s reunion? I thought it was fantastic, and I’m sure Meghan Markle must have broken some dishes in the kitchen.

Taylor Swift’s critically-acclaimed Eras Tour finally landed in London on Friday night and, as expected, there were plenty of noteworthy moments.

The “Fortnight” singer took to the stage at Wembley Stadium to deliver a high-octane show in front of a crowd full of famous faces. Her boyfriend, Kansas City Chiefs tight end Travis Kelce, looked on proudly, as well as her long-time friend, model Cara Delevingne. Meanwhile, Bridgerton’s Nicola Coughlan was photographed at the sold-out show. But it was the royal element that really caught fans’ attention, as Prince William attended the concert with his two eldest children, Prince George, 10, and Princess Charlotte, 9.

Enjoying their royal privileges, William—who was celebrating his 42nd birthday—took his children backstage to meet Swift, and the group immortalized the moment with a selfie. With Swift holding the camera, she took a snap of herself and her boyfriend enjoying time with the royals. Both George and Charlotte could be seen smiling widely.

Taking to Instagram, Swift shared the selfie with her 283 million followers on Saturday afternoon. Speaking out about the reunion, she captioned the image: “Happy Bday, M8! London shows are off to a splendid start.” Marking the international unity, she posted a Union Jack flag alongside the star-spangled banner and a hand-shaking emoji.

But Swift wasn’t the first to share the special moment on Instagram, as just four minutes earlier, the Prince and Princess of Wales’ social media account had shared a photograph that captured Swift taking the selfie with the happy group. The royals’ account captioned the moment by writing:

“Thank you, Taylor Swift, for a great evening!” And it certainly appears that the royals made the most of the concert, as a video of “Prince William vibing and dancing” has since received plenty of attention across social media.
