Beatrice, who is the daughter of the Queen's son Prince Andrew and his ex wife Sarah 'Fergie' Ferguson, is said to have started dating 35-year-old Edo last October.
Still attempting to fly under the radar, the couple attended the annual Berggruen Prize Gala in New York together in December, before ringing in the New Year at Edo's parents' luxury estate on the exclusive island of Lamu off the coast of Kenya.
In March the lovebirds quietly made their first red carpet appearance together for an elegant gala event at the National Portrait Gallery in London.
Both Beatrice and Edo live and work full time in the US.
The ninth-in-line to the throne is a business consultant in New York City while her new beau is the founder and CEO of upscale property development agency Banda.
