ABC News reported that Prince William took his three children, Prince George, Princess Charlotte, and Prince Louis, to Taylor Swift's Eras Tour concert at Wembley Stadium in London. This coincided with William's 42nd birthday, and Kate Middleton shared a heartfelt photo of him with their kids to celebrate. This is not the first time William has shown his love for Swift, as he previously sang with her and Jon Bon Jovi in 2013. The royal family's presence at the concert was just one of many star-studded attendees, including Travis, Jason, and Kylie Kelce, as well as Bridgerton's Nicola Coughlan and Queer Eye's Jonathan Van Ness. Interestingly, the Royal Corps of Army recently performed a version of Swift's song outside Buckingham Palace in honor of her London stop. With Swift set to perform multiple dates at Wembley Stadium this summer, the royal family's support adds even more excitement to the highly anticipated concerts.
