Princess Beatrice and her boyfriend Dave Clark spent Saturday and Sunday on a yacht off the coast of St. Tropez. Beatrice and Dave were spotted strolling through the French town on Friday, and it looks like they kept their vacation going over the weekend. They boarded a small boat that took them to their larger vessel on Saturday and yesterday they changed into new outfits to hang out on the deck. Beatrice and Dave have been all about their relaxing trips this Summer since they already spent a few days in Cap d'Antibes last month. The duo are just one of the exciting royal couples to watch since Prince William and Kate Middleton's North American tour has captured plenty of attention stateside. They wrapped up their travels yesterday and have since returned home to the UK.
