Ah, to be young. And thin. And royal. And to look right, even in a sarong. Such is the lot of Princess Caroline of Monaco's eldest child, Andrea Casiraghi, now 19. A skier, runner and recent high school grad, Andrea was recently snapped spending quality time with an unidentified brunette on the Spanish island of Ibiza. (Notably absent: his usual squeeze, German aristocrat Caroline von Stauffenberg.) Word is that Andrea is being groomed for public life. Presumably that will include wearing pants. "His mother wants him to get more serious," says Monaco-based journalist Kristina Lynn. From the looks of it, mom may have to wait for a rainy day.
