Prince William Celebrates Birthday with His Children at Taylor Swift’s London Concert

The concert doubled as a birthday celebration for Prince William, who turned 42 that day.

Princess Kate was not reported to make the outing with her family. The Princess of Wales, 42, has remained largely out of the public eye in recent months as she continues her cancer treatment.However, the event did not signal a return to public life, with future engagements depending on when she feels able and under the guidance of her medical team.Prince William has previously connected with Swift — in fact, he’s put on a little performance with her! Back in 2013, the royal was led to the stage by Swift during a Centrepoint charity event at Kensington Palace to join Jon Bon Jovi for a rendition of “Livin’ on a Prayer.’ ” The candid moment was described by William’s aides at the time as completely “off the cuff.”
