Taylor Swift takes the perfect royal selfie with William during a performance in London

Taylor Swift took a perfect royal selfie before her performance at Wembley – posing with the Prince of Wales and two young music fans, Prince George and Princess Charlotte.

In a post on X (formerly Twitter), Kensington Palace published a photo of the royal trio with the singer backstage before the concert on Friday evening.

“Thank you Taylor Swift for a great night!” read the caption.

For Prince William, taking his two eldest children to the hottest show in town was a way to score as many daddy points as possible on his 42nd birthday. It was a busy birthday week, as he had just flown in from Germany, where he had attended England’s Euro 2016 match against Denmark the night before.

Swift then posted another selfie featuring Prince William, ten-year-old Prince George, nine-year-old Princess Charlotte and her boyfriend Travis Kelce.

“Happy birthday M8! The London shows are off to a great start,” her post read.

Videos from later that evening, which were widely shared online, appeared to show Prince William dancing to Swift’s upbeat song “Shake It Off.”

Catherine, Princess of Wales, stayed at home with six-year-old Prince Louis.

However, the couple’s youngest child was seen in an official photo released on Friday to mark William’s birthday.

Prince William and pop sensation Swift, 34, have known each other for over a decade.

In 2013, the pair took the stage at a charity event at Kensington Palace to perform “Livin’ On A Prayer” with Jon Bon Jovi.

Swift has traveled across the UK on her “Eras Tour”, with performances in Edinburgh, Liverpool and Cardiff, and has performed her hits for her fans, including from the albums “1989”, “Red” and “Midnights”.

Almost 90,000 fans crowded into Wembley Stadium on Friday, some of them queuing just before dawn.

It was the first of Swift’s eight shows at the stadium, split between this week and August.

Other Swifties in the crowd on Friday included Bridgerton star Nicola Coughlan and Labour leader Sir Keir Starmer.

Queer Eye’s Jonathan Van Ness and model Cara Delevingne were also in the audience, as were Swift’s parents Andrea and Scott.

Swift described London, where she lived for a while early in her career, as “the most exciting city in the world.”
