Pauline Ducruet’s younger half-sister Camille Gottlieb has her own bold sense of style and, it’s hard to miss, a penchant for animals. She has a quantity of dogs that would perhaps best be described as a “fleet,” and she recently visited an elephant orphanage in Sri Lanka (likely a vestige of her time growing up in a circus while her mom dated an elephant trainer).
The late Princess Diana’s 26-year-old niece, Lady Kitty Spencer, was once named “one of the most eligible girls in Britain” by Tatler—and she’s earned a reputation as a woman-about-town, regularly spotted in the front row during fashion month and, on occasion, with fellow It girls like Pixie Lott and Lottie Moss.
Maharaja Padmanabh Singh of Jaipur had the distinct honor of accompanying Reese Witherspoon’s daughter Ava Phillippe to the Bal des Débutantes last month. He doesn’t boast nearly as many Instagram followers as his 18-year-old scion date, but his Instagram does offer a bit of insight: He is, judging by his feed, above all, an avid polo player.
Princess Olympia of Greece turned 21 this summer with a socialite- and model-filled party whose guests included Nikki and Paris Hilton and Poppy Delevingne, as well as her parents, Crown Princess Marie-Chantal and Crown Prince Pavlos. (It was, perhaps, the only thing that could motivate both Hilton siblings to make a pilgrimage to the Cotswolds.)
The Crown Princess Mette-Marit of Norway’s son Marius Borg Høiby celebrated his 20th birthday this year by announcing he would retreat from the public eye while attending university in the United States. (He was, however, never in line for the throne.) But his Instagram remains unprotected, offering his nearly 50,000 followers an inside look at a life spent surfing, skating, and lounging in various hammocks.
Arthur Chatto is 23rd in line for the throne of England, but that didn’t mean he caused any less of a stir when his Instagram surfaced online earlier this year. It’s filled with shirtless selfies, images of his travels in Iceland, Switzerland, and Wales, and behind-the-scenes shots of his days at Eton (and some combination of the three).
There is perhaps no more proud mother than Crown Princess Marie-Chantal of Greece, mother of Olympia. She regularly posts images of her daughter—on stage with Michael Kors, wandering the English moors with her brother, Prince Alexios of Greece—in between promoting her childrenswear line, Marie-Chantal Children.
Prince Constantine Alexios of Greece, the son of Crown Princess Marie-Chantal and brother of Princess Olympia, also holds the distinction of being Prince William’s godson. The Georgetown University freshman fills his Instagram feed with moody black-and-white images, as well as the occasional selfie, broadcasting his antics to his 30,000 followers.
Princess Tatiana of Greece and Denmark goes by a relatively unassuming handle on Instagram—simply @tatianablatnik, which pairs well with her husband's handle @skylightchaser—but don’t be fooled. The co-founder of TRIA ETC, a sustainable fashion brand based in Greece, Princess Tatiana is also an avid foodie, judging by her Instagram feed, where she posts the salads she’s been eating and far-flung destinations to which she’s been traveling lately.
