Dating: Olivier Sarkozy
Age difference: 16 years
For those who worry that the Olsen twins have been cracking up ever since Full House ended, this relationship doesn't debunk the idea. Olivier, an international banker, is the half-brother of the former French President. (That Sarko, who is 12 years older than wife Carla Bruni, might very well have made this list.) Exeter-and St. Andrews-educated Olivier helped large institutions like First Union and Wachovia copulate (in the corporate sense); how often he watched Full House is not known.
