Kate Moss was back on the runway this morning to walk in the Spring 2012 Louis Vuitton show. She also took to the catwalk for her longtime friend Marc Jacobs last season when she memorably strutted her stuff while smoking a cigarette. Many famous faces were on hand to see Kate's latest turn and Marc's new designs. Nicole Richie and Joel Madden popped over to France after spending a weekend in London. Rachel Zoe, Anna Wintour, Uma Thurman, Alexa Chung, and Olivia Wilde were also there. Nicole was evidently impressed to see iconic Kate in the flesh. She tweeted, "Watching Kate Moss close the Louis Vuitton show just killed me." Kate's relationship with Marc and Louis Vuitton was cemented when she inked a deal with their parent company LVMH's Fred jewelry brand. In fact, Kate held a reception for friends at the Ritz hotel last night to celebrate the launch of her new necklaces, rings, and bracelets. Her husband, Jamie Hince, wasn't able to attend, but Kate held court with other pals like Christian Louboutin, Lou Doillon, and Gareth Pugh.
