Prince Constantine-Alexios

Titled heartthrob Constantine-Alexios is the second child and oldest son of Pavlos and Marie-Chantal. 

His godfather? Prince William.

His alma mater? Georgetown.

No big deal.

The 24-year-old crowned creative is a skilled painter, sculptor, and photographer, and, like his sister, has even dabbled in modeling, appearing in a Dior photo book shot by photographer Nikolai von Bismarck (Kate Moss's boyfriend, natch).
