Prince William was dancing like nobody was watching at Taylor Swift's London concert.
That is, if "nobody" was the some 90,000 fellow fans at London's Wembley Arena. While watching the singer's Eras tour show from a VIP box with kids Prince George, 10, and Princess Charlotte, 9, June 21, the Prince of Wales danced to "Shake It Off" and a fan's video of him showcasing his moves has gone viral.
William, who was celebrating his 42nd birthday, and the children got to meet Taylor in person as well. He and the "Blank Space" singer shared photos of themselves taking selfies backstage, with the Grammy winner including her boyfriend Travis Kelce in her pic, making their relationship Instagram official less than a year after they began dating.
"Happy Bday M8!" she captioned her post. "London shows are off to a splendid start."
William, who famously performed with Taylor and Jon Bon Jovi at an event in Kensington Palace in 2013, captioned his pic, shared on his and wife Kate Middleton's Instagram page, "Thank you @taylorswift for a great evening! #LondonTSTheErastour."
The royal family outing comes less than a week after the Princess of Wales joined her husband and kids, including youngest son Prince Louis, 6, at the annual Trooping the Colour parade, a celebration of King Charles III's birthday. It marked Kate's first in-person public appearance since last Christmas and took place almost two months after she revealed her cancer diagnosis. She is still undergoing treatments.
On June 14, Kate shared an update on her health battle, saying on Instagram she hoped to "join a few public engagements over the summer, but equally knowing I am not out of the woods yet."
The princess said she was undergoing chemotherapy and was "making good progress," adding that her "treatment is ongoing and will be for a few more months."
William, the couple's eldest kids and Travis were not the only celebs spotted at Taylor's London concerts this weekend. Also seen at the June 21 show: the athlete's brother Jason Kelce and his wife Kylie Kelce, Bridgerton's Nicola Coughlan, Queer Eye alum Jonathan Van Ness, Leslie Mann and Cara Delevigne. A day later, stars such as Tom Cruise, Ashton Kutcher and wife Mila Kunis, were seen dancing inside a VIP area at the second Wembley show to..."Shake It Off."
