Princess Grace of Monaco
LOOK AT THAT FACE. Feast your eyes on this exquisitely formed human and bask in the sunshine of her extreme beauty. Always appearing flawless and serene, she took her role as Prince Rainier's wife very seriously, giving up acting after only 11 films. For those on the inside, she was said to be enormous fun - David Niven used to sneak her out in his sports car so they could zoom round Monaco hooting with laughter and reciting dirty limericks. Naughty and devastating.
Kate Middleton, Princess of the United Kingdom
There should be hair Oscars. There really should be - because that barnet deserves to be officially recognised for its services to the nation. The lovely thing is, everyone loves us more now because of the Duchess of Cambridge. She always looks wonderful, she's adorable and she doesn't mind getting her hands dirty. She'll ice cupcakes with boy scouts wearing a blindfold, chat to the president of Singapore AND stand in line at the butcher. Also she has a job description that is pretty hard to beat.
Princess Margaret
Capricious, wild and hilarious, Princess Margaret was a legendary beauty. Loved a fag, loved a drink, loved Mustique (where she was given a plot of land and then a five-storey house to go on top of it - nice). She had a complicated love life, a riotous social life and an air of the unpredictable about her. She is said to have can-can**-** ed at an American embassy party and supposedly told French filmmaker Jean Cocteau, 'Disobedience is my joy'.
Princess Gayatri Devi
Once included in Vogue's Ten Most Beautiful Women list, Princess Gayatri Devi was a legendary looker who married Maharaja Sawai Man Singh II and became the Maharani consort of Jaipur. She was mad keen on riding, adored cars, was an excellent shot and spent every summer in Knightsbridge. After independence in India, she ran for parliament, winning in her constituency by a landslide so enormous it made the Guinness Book of Records. She eventually served a five-month spell in prison for alleged tax evasion, but nonchalantly claimed afterwards that 'it wasn't too bad'.
Crown Princess Mary of Denmark
You know how it is. You're just a normal Australian estate agent and one night you go to a pub in Sydney called the Slip Inn with your pal, and it's there you meet some cute boys. You try to work out which of them has a hairy chest and they hilariously end up letting you get hands-on to find out for yourself. It then turns out that one of them is Frederik, Crown Prince of Denmark, who falls for you hook, line and sinker, proposes with a massive emerald-and-diamond engagement ring designed to look like the Danish flag and you end up Crown Princess of Denmark. Imagine if you'd stayed in to watch TV that night?
Princess Maria-Olympia of Greece
Eldest daughter of Crown Princess Marie-Chantal and Crown Prince Pavlos, flaxen-haired teen dream Olympia is happiest in her Givenchy Bambi T**-** shirt, eating mint-and-choc-chip ice cream and watching Clueless. Goddaughter of the Prince of Wales and former Tatler cover star, she is obsessed with Cara Delevingne's Instagram account and raiding her mother's wardrobe for Chanel handbags and Isabel Marant trainers. And no, she did not go out with Prince Harry. Do stop talking about it.
