A glamorous Lauren Sanchez left onlookers stunned after she breezed through the pit-lane in a see-through outfit at the Monaco Grand Prix on Sunday afternoon.
Sanchez and her billionaire beau Jeff Bezos were among the A-list celebrity guests at Formula One's showpiece event in Monte Carlo, and she was certainly dressed for the occasion.
Sanchez, 55, was snapped by photographers as she arrived at the event hand-in-hand with her man, and she wore a floor-length sheer black dress.
As she grinned at the cameras, she showed off her legs after spending a few days sunning herself on her husband-to-be's $500m yacht.
They then took their place on a balcony to take in the F1 race, directly overlooking the cars as they made their way around the principality.
It has been a glitzy few days for the pair, who have been enjoying a romantic Cannes getaway ahead of their highly-anticipated summer wedding.
On Wednesday, Sanchez was spotted sunbathing on the deck of their yacht, and 24 hours later they packed on the PDA at a charity gala at Hotel du Cap-Eden-Roc.
On the yacht, photographers caught Bezos, 61, rubbing suncream onto his fiancée's back as their romance continues to go from strength to strength before they get married.
Bezos first commissioned his super-yacht back in 2018, and it was finally delivered to the Amazon founder in 2023.
At 417 feet, 'Koru' is the largest sailing yacht in the world, and Bezos is often spotted aboard as he gets his money's worth.
The billionaire even proposed to Sanchez aboard the vessel, and it has been reported that they will tie the knot in Venice next month.
In Monaco, meanwhile, Bezos and Sanchez were far from the only celebrities enjoying the festivities.
Hollywood A-lister Patrick Dempsey, model Naomi Campbell and soccer superstar Kylian Mbappe were among the big names on the grid for the most famous race on the calendar.
In the race itself, Lando Norris secured his first ever win on the streets of Monte Carlo, while Monaco native Charles Leclerc finished just behind him in second.
It was a more difficult weekend for the likes of Mercedes - with both cars outside the top 10 - and Lewis Hamilton, who was handed a three-place grid penalty after qualifying.
