Kate Moss grabbed a few friends and hit the town in London last night. She was casual in jeans as she left the Groucho Club, looking quite different from her fancy Wednesday out in her long pink dress. Kate's catching up with pals after traveling to and from Paris multiple times over the last few weeks, and she met up for a recent meal with Stella McCartney and Lily Allen. Kate's buddies have multiple reasons to raise a glass in her honor due to her recent engagement, latest collection for Longchamp, and a new Dior contract. She'll have more opportunities to show off her huge diamonds in the coming weeks as the Fashion Week fun moves on from NYC on to England and France.
