Prince William marked his 42nd birthday by taking his children to a Taylor Swift concert in London. The royal family attended the Eras Tour show at Wembley Stadium, with Prince George, Princess Charlotte, and possibly Prince Louis in tow. Taylor Swift's arrival in London was celebrated with a performance of "Shake It Off" by the royal guard band outside Buckingham Palace. This is not the first time Prince William has interacted with the singer, as they previously sang together at a charity event in 2013. The outing comes amid reports of Kate Middleton's battle with cancer, with the Duchess making her first public appearance since the announcement at the Trooping the Colour festivities. Despite her health struggles, Kate displayed grace and determination during the event, showcasing the resilience and strength of the royal family.
