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).
