Jeff Bezos has his fiancée Lauren Sanchez doing all of the heavy lifting throughout their newest globe-trotting journey — and, no, we’re not speaking about their baggage.

Lauren’s 20-plus carat diamond boulder was on full show — loud, proud and blinding — because the couple pulled into the small village of Beaulieu Friday within the South of France.

She was carrying a low-cut orange maxi gown whereas Jeff saved it informal in a good tee and white pants … aka vacay Bezos-mode.

The ring’s so rattling huge it actually does seem like she’s doing bicep curls when she raises her hand!

TMZ broke the story … Sanchezos initially tried to maintain their engagement below wraps after he popped the query in Spain.

She turned the ring round so the diamond wasn’t displaying … however as soon as that they had some pals aboard the $500 million superyacht, there was no protecting it secret.

BTW, they’re again aboard the Koru for this journey proper now. As we have seen in latest days, Jeff is doing a little work … as her private photog — he snapped pictures of Lauren rocking a bikini on the yacht’s deck.
