Supermodel Kate Moss celebrated turning 40 on Thursday (16Jan14) with a star-studded party in London. The blonde beauty was joined by a host of celebrity friends including fellow catwalk queen Naomi Campbell, actress Sadie Frost, revered photographer Mario Testino, and disgraced fashion designer John Galliano to mark the milestone. The group, which also included Moss' rocker husband Jamie Hince and her mother Linda Rosina, enjoyed Champagne and cocktails during the bash at the plush 34 restaurant in London's Mayfair, racking up a $8,000 (£5,000) bill, according to Britain's Daily Mail. The publication reports Moss was overheard telling fellow revellers, "I might be 40 but I still know how to party." They eventually left the venue in the early evening and headed to the city's Dorchester hotel, where the party continued until the early hours of Friday (17Jan14). Moss reportedly recently returned from Sir Richard Branson's luxury holiday retreat on Necker Island in the Caribbean, where she had been relaxing ahead of her milestone birthday.
