Kate Moss bares the Parisian cold in a sheer lace dress and silk cape as she celebrates her 50th birthday in the French capital with boyfriend Nikolai Von Bismark, daughter Lila and close friends Stella McCartney and Charlotte Tilbury

If 50 is the new 40, Kate Moss made sure she was appropriately dressed as she celebrated her milestone 50th birthday at an upscale Paris restaurant on Tuesday evening.

The supermodel defied her age in a stunning sheer lace dress and black silk cape as she stepped out of her chauffeur-driven car on a pair of stylish open-toe heels and made her way into the 41 Avenue Gabriel venue.

She was in good company that evening: her long-time boyfriend Nikolai Von Bismark, her daughter Lila Hack-Moss and designers Stella McCartney and Charlotte Tilbury were on hand to help her celebrate with a helping of the very best French haute cuisine.

After enjoying a celebratory brunch in the capital that day, Kate had decided to end her birthday at Laurent, a stunning upscale restaurant in a historic mansion in central Paris with garden tables and its own wine cellar.

The supermodel, who has been planning her 50th birthday celebrations for a “long time,” showed off her stunning figure in an ultra-chic lace dress for her big night in the City of Light.

Kate wore her stunning black floral dress over a skimpy bodysuit and added extra sparkle with diamond bracelets.

She completed the look with a dramatic champagne-lined satin cape and slipped on silver strappy heels.

The model flew to Paris to celebrate the milestone.

During the outing, the star was seen unzipping a white long-sleeved shirt with a black pattern print.

Kate admired the gift, which apparently came from a friend who was also at the brunch with Lila and Nikolai.

She flew from Oxford to the French capital on a private jet that could accommodate up to seven VIP guests ahead of her party on Tuesday.

And it's believed Kate will be joined at the Ritz for the celebrations by celebrity friends including Noel Gallagher.

Lila carried heavy bags from her home in London before flying to Paris and joining her famous mother for the celebrations.

Lila shared a picture of the Eiffel Tower on her Instagram Story and expressed excitement as preparations for the big night were officially underway.

A source told Web: “Kate has been planning a big party at the Ritz in Paris for a long time.”

“And finally the day has come and all her close friends and family are jetting to the capital to celebrate her special day.”

“As a world-famous supermodel, no one expected anything less from Kate than to host her party at the Ritz in Paris that was almost as fabulous as she was.”

“It's going to be a night to remember, she can't wait to get dressed up and dance the night away.”

Web understands the private jet Kate flew to Paris on would have cost £10,000 and the former party girl made sure she arrived in the City of Light in style.

Kate's flight took off after 4pm on Monday and she landed in France shortly afterwards.

A source added: “Kate loves the Ritz and always stays at the hotel when she's in Paris.”

“She wants to keep her soirée as private as possible and knows she can trust the staff there.”
