10. Princess Mary — Denmark
Princess Mary is living proof that fairy tales can come true. A native of Hobart, Tasmania, this elegant 39-year-old was working at an Australian advertising agency in 2000 when she literally bumped into a handsome young man named “Fred” in a crowded Sydney pub. It wasn’t until a half hour later that a friend informed her that “Fred” was in fact Frederik, Crown Prince of Denmark.
The pair fell head over heels in love and were married four years later on May 14, 2004 in a lavish ceremony conducted at Copenhagen Cathedral. Mary has since become a beloved figure in Denmark where, according to a recent poll, 75 % of Danes believe she will make an excellent queen.
09. Princess Sirivannavari — Thailand
The only thing more alluring than an exotic princess is an exotic princess with a net worth of $35 billion. The granddaughter of Thailand's King Bhumibol Adulyadej, this fabulously wealthy 24-year-old is also an accomplished designer whose signature fashion line has been met with rave reviews at shows in Paris and Bangkok.
Given her success and royal lineage, it’s hardly surprising that so many men have designs of their own on Princess Sirivannavari -- and that she makes our list of the top 10 hottest princesses.
08. Princess Eugenie — UK
There’s a fine line between being a royal and being a royal pain in the ass, and it’s one that Princess Eugenie of York treads on a daily basis. Hailed by the press as “the royal family’s new bad girl,” Prince Andrew’s youngest daughter raised eyebrows and libidos across the UK in 2009 when she was spotted stealing bikini tops and allowing her breasts to be fondled by her female friends during a trip to Thailand.
Two years have passed since that naughty episode, but this 21-year-old wild child doesn’t seem to have settled down as she continues to make headlines by smoking, frequenting pole-dancing clubs and running naked on school grounds.
07. Princess Sonam — Bhutan
Princess Sonam is proof that brains and beauty aren’t mutually exclusive. The daughter of the Fourth King of Bhutan, this stunning 30-year-old has a degree in international relations from Stanford University and a Master of Laws from Harvard. If you ask nicely enough, she might even show you her legal briefs.
06. Princess Alexandra — Luxembourg
Anyone up for a game of tennis? You’d be hard pressed to find a better doubles partner than Princess Alexandra. The only daughter of Grand Duke Henri and Grand Duchess Maria Teresa of Luxembourg, this eye-catching 20-year-old can usually be found patrolling the baselines at Franciscan University of Steubenville, where’s she’s a freshman on the varsity tennis team. A good sport through and through, Alexandra is also known to enjoy dancing, skiing, waterskiing, and swimming.
05. Charlene Wittstock — Monaco
There are few women on our list of the top 10 hottest princesses who fill out a Speedo quite as impressively as Charlene Wittstock. A former champion swimmer, this bodacious blond powered South Africa’s 4 x 100 medley team to a fifth-place finish at the Sydney Olympics in 2000.
Wittstock’s flawless physique soon caught the attention of Monaco’s Prince Albert II, and the pair embarked on a fairy-tale romance, culminating in their engagement on June 23, 2010. They are now scheduled to make waves all around the world with a lavish wedding scheduled for July 8, 2011.
04. Charlotte Casiraghi — Monaco
It’s nearly impossible to look at Charlotte Casiraghi without instantly thinking of her grandmother, Grace Kelly. After all, this ethereal 24-year-old possesses the same beauty and elegance that made Kelly a celebrated Hollywood star more than six decades ago. Mind you, Casiraghi has far more than just dazzling good looks and impeccable genes to her credit.
She is also a Sorbonne graduate and an accomplished journalist who has worked as the editor-at-large of Above, a cutting-edge luxury magazine published in London. A close friend of designers Valentino and Karl Lagerfeld, Casiraghi is currently fourth in line to the throne of Monaco.
03. Princess Madeleine — Sweden
If we had an eveningwear competition, Princess Madeleine would surely come in first place. The youngest child of King Carl XVI Gustaf and Queen Silvia of Sweden, this buxom 28-year-old blonde has been known to draw audible gasps with her precariously high hemlines and plunging necklines.
Known as “Len” to her closest friends, Princess Madeleine is now back on the market since breaking off her engagement to Jonas Bergstrom after he was caught cheating on her with a college student.
02. Princess Letizia — Spain
Princess Letizia knows a thing or two about making headlines. A former journalist for Bloomberg and CNN+, this sultry Spaniard was covering the sinking of an oil tanker in 2002 when she first met Felipe, Prince of Asturias. The pair soon fell in love and were married two years later on May 22, 2004. Letizia has since traded in her microphone for a sceptre as she prepares to become her nation’s first Spanish-born queen since 1879.
