Kate Moss celebrated the launch of her new handbag collection for Longchamp at the company's store in London last night. She's continuing to promote her work with the brand, as she starts to lighten her workload with Topshop. Kate's bash was well-timed to coordinate with London Fashion Week, which she helped kick off a few days ago at a party thrown by her ex Jefferson Hack. She broke from the posing, though, to attend her friend Alexander McQueen's memorial service on Monday alongside other famous faces like Sarah Jessica Parker and Anna Wintour. Kate is a public supporter of fashion in England, but she's notoriously quiet when it comes to her privacy — one chapter in her life is going out into the open soon when Russell Brand shares about their brief affair in his upcoming Booky Wook 2.
