It's impossible to escape the big birthday news this week: Kate Moss is turning 40.

From the sheer amount of coverage of this humble event, it's clear to see that we are a nation obsessed – even after all these years. The thing is, Kate Moss is not only a supermodel; she's also our chosen representative in the world of parties. Since her very first years in the industry, she's been the life and soul of every event she has attended. She's the girl everybody wants to sit next to because she always looks like she's having the time of her life – usually with a fag in one hand and a flute of champagne in the other. 

Some of her friends are bona fide megastars, while others in her loyal inner circle seemed to become famous simply because she loved them. So on this momentous occasion, take a look through our gallery for photographic proof: Kate Moss has ruled the cool crowd since day one.
