Taylor Swift Takes Selfie With Prince William and Children as Royal Celebrates Birthday at London Eras Tour Show

Friday night’s show was the first of three at London’s Wembley Stadium. During the surprise song segment of the performance, Swift delivered the live debut of “Tortured Poets Department” track “The Black Dog” — named after a pub in Vauxhall — which was mashed up with “Come Back Be Here” and “Maroon.” She also played a medley of “Hits Different” and “Death by a Thousand Cuts.”

During the “1989” era of the show, Prince William was spotted dancing and singing along enthusiastically to “Shake It Off,” spurring chatter on social media. “That’s our next King of England and I’m so here for it,” one user wrote. Though his wife, Kate Middleton, recently made her first public appearance since her cancer diagnosis at last weekend’s Trooping the Colour event, she was not in attendance at the concert.
