Time to start the royal (well, princely) wedding countdown again, hatters -- Princess Caroline's baby boy is getting hitched! Andrea Casiraghi -- who, even without a title, is currently second in line to the Monegasque throne -- is engaged to his longtime girlfriend, Tatiana Santo Domingo, and to celebrate, of course, they threw a big bash on a yacht. (What, you don't have a yacht? Psssh. Plebians.)
And, even better? The yacht party theme was apparently RAGAMUFFINS IN HATS. Read on, hatters. Trust me: you won't regret it.
