Mirrorpix / Splash NewsPrince William must be gearing up to give the royal baby plenty of raspberries!
The 30-year-old expectant father playfully stuck out his tongue Monday at that St. George's Chapel in Windsor Castle for the Order of the Garter. Kate Middleton wasn't present for the big day, but her husband and Prince Charles accompanied Queen Elizabeth II for the ceremony, which inducted 24 Knights to England's highest order of chivalry.
Wills looked a tad uncomfortable in the traditional blue velvet robe. Perhaps, though, it was the super-sized white feather in his black hat that caused him to good-naturedly stick out his tongue.
His pregnant wife's final public appearance before giving birth was the Queen's birthday parade on Saturday. Kate's final solo public appearance prior to welcoming her and Wills' little one was last Friday when she christened a Royal Princess cruise ship.
And while we won't be seeing much more of Kate out and about (at least for official reasons), she and Wills will surely celebrate the future King turning the big 3-1 this Friday. And after that, considering Kate's mid-July due date, perhaps the royal baby will have the next big birthday in the family!
