Kate Moss channels the Parisian chill 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 friend Stella McCartney

If 50 is the new 40, Kate Moss made sure she was dressed appropriately as she celebrated her milestone 50th birthday at a chic restaurant in Paris 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 in a pair of stylish open-toe heels and drove into the venue at 41 Avenue Gabriel.

She was in good company that evening, with long-term boyfriend Nikolai Von Bismark, daughter Lila Hack-Moss and designer friends Stella McCartney and Charlotte Tilbury, all on hand to help her celebrate with helpings of the very best Haute French cuisine.

After enjoying a festive brunch in the capital earlier that day, Kate had chosen to round off her birthday at Laurent, a beautiful luxury restaurant in a legendary mansion in central Paris with garden tables and its own wine cellar.

The iconic model, who had been planning the party for 'a long time', showed off her stunning figure in the ultra-chic dress for her big night in the City of Light.

Kate wore her stunning black floral dress over a skimpy bodysuit and added extra glitz with diamond bracelets and jewel-encrusted heels.

Her escort for the evening Nikolai, 37, looked dapper in a tailored black tuxedo, which he paired with a stylish fur-trimmed coat.

Meanwhile, daughter Lila, 21, was also dressed to impress in a chic black mini dress which she teamed with a double-breasted coat.

She strutted her stuff in sky-high heels as she attended the event by her boyfriend Yoni Helbitz, 23, whose identity was exclusively revealed by MailOnline last year.

Fashion designer Stella, 52, was very much in the party mood as she arrived in a thigh-skimming tiger print mini dress as she showed off her long, toned legs.

Kate's longtime friend stunned in the draped Greek-inspired dress and oozed confidence as she walked into the chic event.

Kate flew to the French capital from Oxford via a private jet with seating for seven VIP guests ahead of her party.

Lila was pictured carrying heavy bags from her London home before flying to Paris where she joined her famous mother for the festivities.

Kate forwent a necklace and let the outfit speak for itself, opting for dangling diamond earrings instead

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