The ninth-in-line to the throne and her boyfriend, Edoardo Mapelli Mozzi, were spotted arriving at the exclusive cliffside village of Positano on Italy's stunning Amalfi Coast.
The couple chartered a boat, by a company which offers private tours from €1,500 to visit a tiny, pebble beach only accessible by boat.
Locals said Beatrice, 31, and her boyfriend spent two hours on the pebble beachfront, before dining at Da Adolfo restaurant and beach club, where lunch costs around €100.
The pair are currently holidaying together in the country amid speculation they could be tying the knot soon, with Italy favoured to be the chosen location.
The holiday comes just a few weeks after, Princess Beatrice’s mother, Sarah Ferguson, the Duchess of York, was pictured touring one of the most romantic wedding venues in rural Tuscany.
Her chauffeur tagged Villa Cetinale in an Instagram snap of the duchess, along with a company called Iles Events - which specialises in Italian destination weddings.
An onlooker who spotted Beatrice and Edo as they holidayed said they looked very happy and relaxed.
"They looked very much in love and happy. It would not be a shock to see theirs being the next royal wedding,” she said.
Princess Beatrice and Edo started dating in mid-September after being introduced by friends in common, and immediately hit it off, according to friends of the couple.
Rumours began swirling earlier this year that the pair are set to marry, after moving in together at St James’s Palace.
Despite no official engagement, the couple are reportedly considering marrying at the end of 2019 or early 2020.
Edo, as he is known to his friends, works as the CEO of Banda Property, which he founded in 2007.
He’s the son of Count Alessandro Mapelli Mozzi and Nikki Shale and has a two year-old son Christopher ‘Wolfie’ Woolf from his previous marriage with Chinese-American architect Dara Huang.
Beatrice split from her previous boyfriend American Dave Clark in 2016 after a decade together.
Clark married Lynn Anderson, a New York advertising executive, in a lavish wedding ceremony in Puglia, Italy in July 2018.
And maybe Beatrice will follow suit in following her ex down the aisle in the country.
If they did choose to marry in Italy they would be in good company. Earlier this year Heidi Klum and musician Tom Kaulitz tied the knot on a boat in Capri, Italy.
