Prince William celebrated his 42nd birthday at Taylor Swift’s Eras Tour performance at Wembley Stadium June 21 alongside children Prince George, 10, Princess Charlotte, 9, and Prince Louis, 6.

Prince William is celebrating like it’s his birthday, every day.

The Prince of Wales marked his 42nd birthday with a very special outing as he took his children Prince George, 10, Princess Charlotte, 9, and Prince Louis, 6, to see Taylor Swift perform at London’s Wembley Stadium June 21, royal reporter Roya Nikkhah confirmed on X.

William’s wife Kate Middleton did not appear to be at the show alongside her family, although she did have a sweet birthday message for her husband of 13 years earlier in the day.

“Happy birthday Papa,” she posted on Instagram, alongside a photo of William and his children jumping on the beach, “we all love you so much! Cx.”

And while Kate has largely stayed out of the public eye since sharing her cancer diagnosis in March, the 42-year-old did join the royal family for her first public appearance at the Trooping of the Colours ceremony on June 15. The Princess of Wales—donning a black-and-white Jenny Packham dress and Philip Treacy hat—appeared with her family on the Buckingham Palace balcony as they watched the Royal Air Force fly past.

As for William, this is far from the first time he and Taylor have crossed paths. In fact, Miss Americana and the real-life prince previously took the stage together alongside Jon Bon Jovi for a performance of “Livin’ on a Prayer” at a charity event in 2013. And as Taylor explained the following year, it was truly a wild moment.

“Yeah, it was insane,” she said, “and I was very nervous for the whole thing because it was at Kensington Palace and it was my first royal encounter of sorts.”

According to the 34-year-old, before Jon started to sing, he pointed to William, “and said something like, ‘I hear you like to do this at karaoke night, karaoke boy.’”

“He starts the song and Prince William looks over at me and says, ‘I don’t remember it now. It’s all gone now. I don’t remember the song now.’ Kinda freaking out a little bit,” she continued. “He just looks at me and is like, ‘You gotta go with me’ and I was like, ‘OK,’ and we got up there and started singing ‘Livin’ on a Prayer.’ Like, I died.

Unfortunately William did not appear to take the stage at Wembley Stadium during the Eras Tour, but the royals were in good company, as Taylor’s boyfriend Travis Kelce was also spotted in the audience, alongside his brother Jason Kelce and his wife Kylie Kelce.
