Harry Styles, Sir Tom Jones, Sienna Miller, Kate Moss and Rita Ora were among the stars who turned out for a glitzy party in London on Monday night (02Dec13) to celebrate Playboy's 60th anniversary. Hugh Hefner's saucy publication marks six decades in print this year (13) and British supermodel Kate Moss was chosen to don the iconic bunny outfit to grace the cover of the 60th anniversary December issue. The publication's milestone was marked with a lavish bash at the Playboy Club in London on Monday, hosted by Moss and designer Marc Jacobs, and the party attracted big name stars including Sir Tom Jones, One Direction heartthrob Styles, and actress Miller. Model Daisy Lowe was also in attendance, along with pop singers Rita Ora and Matt Goss and TV presenter Alexa Chung, rocker Noel Gallagher, model/actress Rosie Huntington-Whiteley, Hayley Atwell and Bob Geldof. It was a busy night for both Styles and Moss, as they had both picked up prizes at the British Fashion Awards in the U.K. capital earlier in the evening.
