Princess Olympia of Greece vacation with boyfriend Peregrine Pearson and her family

Princess Olympia of Greece has flown to Athens with her family and her handsome British aristo-beau.

The 24-year-old socialite, who grew up in Chelsea and is Prince Charles’ goddaughter, took the sights along with her four brothers and their parents, Crown Prince Pavlos and Princess Marie-Chantal of Greece.

She is joined by her rambunctious boyfriend Peregrine Pearson, son and heir to the 4th Viscount Cowdray, whose family has a known fortune of £224 million.

Perry’s father owns a significant portion of the Pearson media empire, as well as the 16,500-acre West Sussex estate, which is home to the Cowdray Park polo club, where Princes William and Harry played.

Perry’s Instagram account, which prefers to stay out of the limelight, is private and he rarely makes public appearances with Olympia.

But the couple, who have been dating for a year, couldn’t resist documenting their Greek vacation and radiant Olympia shared a photo of them together on Instagram.

Olympia’s grandfather is King Constantine, a relative of Prince Philip, who was expelled from Greece after the 1967 coup. The family continues to use their royal titles decades after the abolition of the monarchy.

Typically stylish, Olympia opted for a flirty brown and white polka dot sundress with thin straps for a day out with her family and her boyfriend.

Perry, for his part, looked handsome in a light blue linen shirt and shorts.

Olympia, who is close to all four of her brothers, posted photos of her siblings exploring the city and chatting happily over a leisurely meal at an open-air restaurant. She also posted a photo of a romantic sunset over the city.

Proud mother Marie-Chantal also posted a handful of snaps on Instagram, including one of the whole family together.

Pavlos and Marie-Chantal spend most of their time in New York, but usually head to Europe for the summer.

Olympia has already enjoyed a stop in London, where she has undoubtedly spent time with Perry.

She also spoke to her uncle Prince Philippos of Greece, the godson of Princess Diana, and his wife Nina.

Philippos, a New York-based hedge fund analyst, and Nina posed with Olympia outside Somerset House in London, where the photography of Philippos’ brother Nikolaos is displayed as part of the London Design Biennale.

Nina and Philippos married in a small private ceremony in the glitzy Swiss ski resort of St. Moritz in December, with only their fathers King Constantine, 80, and Thomas Flohr, 60, in attendance due to Covid-19 restrictions.

In May, the couple celebrated their wedding with a second quiet wedding hosted by Vogue writer Alice Naylor-Leyland and her husband Tom at their home of Stibbington House in Cambridge, with the couple decorating their home for the occasion with white balloons and blue flowers.
