The loved-up couple has been enjoying a relaxing and romantic getaway in Greece alongside the brunette beauty's ex-boyfriend Tony Gonzalez, his wife October, and a few of their other pals - including Kim Kardashian .

And, the future Mrs. Bezos has made sure to show off her sizzling physique while on the lavish vacation.

Most recently, Lauren took to Instagram to put on a stylish display, wowing in a crochet dress with a series of cutouts that accentuated her trim waistline.

The mom-of-three - who is engaged to the 60-year-old Amazon founder - paraded her fit figure in the tiny number as she held her long locks back in the wind.

Lauren dazzled in the white dress, which featured a strapless neckline and a crochet pattern.

The former journalist opted for minimal makeup, which complemented her natural beauty.

She showed fans that she was really was more in love with her partner and her life than ever before by captioning the photo with a simple heart.

Lauren and Jeff have been island hopping on his luxury $500 million mega yacht Koru since the beginning of June - with Koru meaning 'new beginnings' in Maori.

Jeff's 230-foot tall yacht, which he commissioned in 2018, currently holds the record for being the world's tallest superyacht.

The Koru is the second-largest sailing ship in the world.

The superyacht holds a special place for the couple, with Lauren and Jeff getting engaged there in early 2023.

Lauren detailed the heartwarming moment Jeff got down on one knee while speaking to Vogue last year.

She recalled how Jeff popped the question on the $500million superyacht after they enjoyed a romantic dinner under the stars together.

Lauren said Jeff concealed the huge diamond ring under her pillow, adding that she almost 'blacked out' when she discovered it at the end of their romantic evening.

The couple recently relocated from Seattle, Washington, to Indian Creek Island in Florida - with Jeff purchasing three mansions on the island, totaling a whopping $237 million.
