Stella McCartney’s Stellar 40th Birthday Bash!

If anyone’s going to have a seriously star-studded guest list at their 40th birthday celebrations, it’s Stella McCartney, so we weren’t surprised to see her celeb pals out in force to party last night.

Kate Moss, Cameron Diaz, Gwen Stefani and Liv Tyler all turned out to toast the fashion designer turning 40 at luxe London pub The Cow – we bet that caused a stir among the locals! Kate accessorised her leopard skinny jeans and black shirt with hubby Jamie Hince, while Cameron, Liv and Gwen were all chicly dressed to beat the autumn chill (in Stella McCartney, we’re sure). We’ve got to say, they all left looking rather fresh-faced – we’re hoping there was a secret champagne-fuelled after-party somewhere, ladies? GG
