PRINCE HARRY, 26
Prince Harry stepped out of big brother William's shadow long ago, establishing himself as a carefree (and now single), loyal royal. The second son of Prince Charles, who is entitled to a multi-million dollar inheritance from late mother Princess Diana, admirably serves his country as a second lieutenant in the Blues and Royals regiment of the Household Cavalry.

PRINCE CARL PHILIP, 31
Known for his star-worthy good looks – hello Orlando Bloom! – Prince Carl Philip recently reentered the market after ending a 10-year relationship. The only son of King Carl XVI Gustaf and Queen Silvia, who studied graphic design at Stockholm's Forsbergs School of Design and Rhode Island School of Design, is second in line for the Swedish throne, behind older sister Victoria.

ANDREA CASIRAGHI, 26
The eldest son of Princess Caroline – and grandson of Grace Kelly – is second in line for Monaco's throne should uncle Prince Albert fail to produce an heir. But even without royal pedigree (because Casiraghi's father was a commoner), the playboy remains a catch: He has homes in Monaco, Paris, and Saint-Rémy-de-Provence, France.

PRINCE PHILIPPOS, 24
The youngest son of deposed King Constantine of Greece and Queen Anne-Marie of Denmark, Prince Philippos is a royal without a palace. But the Georgetown University graduate is making his own way in the world, recently relocating to New York to work for hedge fund EIM Group.

PRINCE AMEDEO, 24
Having graduated in 2008 from the London School of Economics, Prince Amedeo is not only book smart he's downright patriotic: He spent time at Belgium's Royal Military Academy and played for LSE's rugby team.

Sheikh Hamdan bin Mohammed bin Rashid Al Maktoum, 28
Country: United Arab Emirates
Despite being named crown prince of Dubai, Maktoum – who goes by "Fazza," which means "the courageous" – is far from resting on his gilded laurels. The heir to a whopping $12 billion fortune is a graduate of Britain's Royal Military Academy Sandhurst and serves as chairman of the Dubai Executive Council.
