In his first official appearance since the royal tour, Prince William threw back a shot of rum during a submarine tour in Hampshire, England, on Monday. While visiting the Royal Navy Submarine Museum, the Duke of Cambridge checked out a recently restored World War II submarine before drinking a shot of Pusser's British Navy Rum, toasting Royal Navy Submarine Vice Admiral Sir Tim McClement. After taking the drink, Prince William joked, "Where's everyone else's rum?" During the tour, he also gave a nod to his little one, Prince George, saying the group was lucky he wasn't there "up to all sorts of mischief, pulling things."
The tour marked the start of an exciting week for Prince William, who is set to host a charity dinner at Windsor Castle later this week. Stars like Benedict Cumberbatch, Kate Moss, Cate Blanchett, and Cara Delevingne are expected to attend the event, which will raise money for the Royal Marsden Cancer Charity. In the meantime, take a look at the best pictures from Prince William's submarine visit.
