Lauren Sanchez, 54, stuns in a strapless sheer black dress as she joins her billionaire fiancé Jeff Bezos, 60, at Dolce & Gabbana show in Sardinia

Lauren Sanchez stunned as she joined her billionaire fiancé Jeff Bezos at the star-studded Dolce & Gabbana show in Sardinia on Tuesday evening. 

The beauty, 54, and her businessman partner, 60, looked every inch the glamorous couple as they arrived at the high fashion event.

Lauren showed off her gorgeous curves in a strapless black sheer dress which revealed her toned physique.

The lace number featured pretty ruffle detailing and was cinched in at the waist with a corset-style top.

She completed the look with platform heels and accessorised with dangly silver earrings to add a touch more glamour. 

Beside her Jeff looked dapper in a black suit and dark shades as he carried his drink with him.

It comes after earlier this week Lauren wowed as she soaked up the sun in an ultra-mini white dress while on Jeff's $500 million yacht. 

The loved-up couple had 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 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 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. 

She showed off her strong arms as she kept her hair from blowing in the wind. 

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. 

Her most recent snap comes after she touted her fun-filled lifestyle online. 

Over the weekend, the former journalist proved she was still young at heart as she jumped on a jet ski and rode the waves while sizzling in a gold bikini. 

The skimpy swimsuit put her ample assets on full display as she and Jeff had a blast on the shimmering blue waters of the Aegean Sea.

Kim - who has long hailed Lauren as one of her best friends for 'life' - also joined the couple in her own jet ski.

The reality TV star, 43, who was joined by TV personality Olivia Pierson on a separate jet ski, looked at ease.

She slipped into a silver co-ord with a bikini top and biker-style shorts before stopping to pose up a storm for a series of selfies.

Lauren and Kim have formed a tight friendship in recent years - with the pair regularly stepping out for dinners together, along with Jeff, who is also close with Kris Jenner.

Just a few days before Lauren and Jeff's trip to Greece at the beginning of June, the former reporter put on another dazzling display as she and Jeff celebrated her eldest son's graduation from college.

They were joined by the Gonzalez family, with all participating in a graduation photoshoot together, before heading out to dinner to honor Nikko.

The proud mom shared a montage of photos and clips from the festivities in a video posted to her Instagram afterward.

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.
