Prince William's single younger brother, who is currently serving as a military helicopter co-pilot in Afghanistan, has topped the Top 40 Bachelors list compiled by America's Town & Country magazine.
Harry made the list ahead of Hollywood's most famous bachelors - Clooney and Nicholson.
Magazine editors write of the 28-year-old royal, ""Prince William's baby brother flirts and flies Apache helicopters with equal aplomb... He loves dressing up - in everything from ill-fated fancy dress to his birthday suit.""
The list also featured a number of other European royals, including Prince Philippos of Greece and Denmark, Grace Kelly's grandson Pierre Rainier Stefano Casiraghi of Monaco, Prince Carl Philip of Sweden, and Prince Amedeo of Belgium.
A number of sports stars were also granted top bachelor status - golfer Adam Scott, American football player Tim Tebow, and baseball star Jeremy Lin were all included, while celebrity offspring also featured highly.
Bryan Ferry's four sons, Merlin, Isaac, Otis, and Tara, won a mention, along with Arnold Schwarzenegger's son Patrick and Clint Eastwood's actor son Scott. Taylor Swift's ex-boyfriend Conor Kennedy was also included, along with twins Tyler and Cameron Winklevoss and Hollywood veteran George Hamilton.
