Prince William attended on Friday, his 42nd birthday, to the Taylor Swift concert in London. William was accompanied by his two oldest children, Jorge, 10, and Carlota, 9.

Kensington Palace published an X photo in which the American singer is seen taking a selfie with the heir to the British throne and the children backstage before the concert at Wembley Stadium.

“Thank you @taylorswift13 for a great evening!” says the message alongside the image.

For his part, Swift spread another selfie of her with Guillermo, the children and her boyfriend, Travis Kelce. “Happy birthday M8! The London concerts are off to a splendid start,” he said.

The Princess of Wales, who is in oncological treatment, stayed at home with the couple’s young son, Luis, 6 years old. On the occasion of Guillermo’s 42nd birthday, Catalina posted on X on Friday a photo she took of her husband jumping with her three children, with the message “we love you very much.”
