Princess Caroline of Monaco drinks still water

Princess Caroline of Monaco (right) appears to be drinking still water, while her future sister-in-law Charlene Wittstock (left) seems to prefer sparkling, judging by the bubbles in her glass. (Surely, though, Caroline's choice is not *tap* water.) The two were appearing at International Monte Carlo Jumping in Monaco on Thursday, June 23, 2011. This was shortly before Wittstock and her fiancee, Prince Albert of Monaco, were married on July 1, 2011.
