Nobody Had More Fun at the London Marathon Than Prince William . . . NOBODY

Prince William, Kate Middleton, and Prince Harry kicked off the London Marathon on Sunday, where their mental health campaign, Heads Together, was the official sponsor. While the trio, who recently sat down together to discuss Princess Diana's death, shared a few laughs and cheered on runners from the sidelines, Prince William in particular seemed to really let loose. The British royal, who sadly left kids Prince George and Princess Charlotte at home for the outing, blessed us with so many funny faces during the race that we didn't even bother counting. In addition to getting splashed with water, William also passionately shouted words of encouragement at people, blew a horn in Kate's ear, and gave a thumbs up. We love seeing the royals at their official events and all, but there's really nothing like watching them have a genuinely good time.
