“They have known each other a very long time. They are very close.”
Another source told The Sun: “Things are moving very quickly and it wouldn’t surprise anyone if they got engaged within a short period of time.
“They could even be tying the knot in 2019 — it’s already been discussed by her friends.”
Princess Beatrice confirmed the pair were dating in November 2018.
Edo is a close friend of the family and has known Beatrice since she was little.
British punters are currently placing bets on the couple getting engaged this year.
"It looks as though Princess Beatrice will be the next Royal name to tie the knot, and we're not ruling out an engagement as early as this year," a Ladbrokes spokesperson said.
