Prince Wenzeslaus of Liechtenstein
With 35,000 subjects, Wenzeslaus exercises fractionally less global influence than a North Shields councillor. But what he lacks in dominion, he makes up for in cash; his family is considered the richest monarchy in Europe. No wonder "Prince Wence" appears regularly on Hot Royal lists. And no wonder (sigh) he's dating Victoria's Secret model Adriana Lima.Prince Philippos of Greece and Denmark
Born 13 years after Greece officially abolished its monarchy, he at least he keeps the title. Currently studying at university in Washington DC, he boasts a tidy line in bow ties.
Big brother may be taken, but Hazza, with his freckles and insouciant charm, has long been the preferred royal among those who like their princes a little naughty, less bound by birthright and with their hair intact. At his best posing sans shirt in the desert, rather than pining for on/off squeeze Chelsea, he even does charity work, helping kids in Lesotho.
Prince Carl Philip of Sweden
With hair and looks to make Hugh Grant weep, Carl-Philip, 31, has a playboy rep. The model Sofia Hellqvist is his latest squeeze reported in the Swedish press. With an interest in graphic design and illustration, he has studied at the National Geographic Society in Washington, and served in the Swedish navy.
Pierre Casiraghi of Monaco
The son of Princess Caroline began making frequent appearances in gossip columns during his time studying in Milan. Although he left without a degree, he was linked to a string of women including Alice Dellal, Caroline Winberg and his current girlfriend, Beatrice Borromeo.
Prince Albert von Thurn und Taxis
He has no actual dominion, but who cares? Albert made the Forbes rich list aged nine and now, at 24, is worth $2bn. He studies business and theology at Edinburgh and likes car racing, although his boisterous sideburns suggest that money can't buy taste – or at least decent facial hair.
Prince Azim of Brunei
The joker in the pack of international princes caught our eye last year by inviting Sophia Loren, Ursula Andress and Joan Collins, as well as 230 of his closest pals, to his 26th party. Chaka Kahn was the turn. Set to inherit a hefty chunk of his father's £25bn oil fortune, he once claimed to be "addicted" to Mahiki – the club favoured by William and Harry.
Prince Amedeo of Belgium
The heir to the House of Austria-Este is reputed to be serious, thoughtful and ambitious. Educated at London School of Economics, he now works for Deloitte in New York, where he ran the marathon in 2008. His less hunky brother Joachim does, however, have the best title: Prince Imperial of Austria, Prince Royal of Hungary and Bohemia.Reuse content
