Kate’s last Father’s Day before celebrating with Prince William and a tiny plus-one? The Duchess of Cambridge spent Sunday with 28 “inner city” kids on a campground in part of an event for the students of King Solomon Academy Primary School. Kate thought the tents of the 8- and 9-year-olds were “marvelous.” By the campfire, Middleton said that Prince William is “sweet” and “spoils” her. So was she able to rough it? She did wear a $500 pair of leather boots.
