One of the several parties going on last night on our island included a celebratory bash put on by Dior Beauty to celebrate Tinsley Mortimer's cameo on Season Two of Gossip Girl. The guests looked on top of the world on the Empire Hotel's rooftop, and even Tins' hubby Topper showed up to support his gal.  Other guests included: Fabiola Beracasa, Peter Davis, Genevieve Jones, Lindsay Trulli, Jessica Stam, Derek Blasberg, Saree Kayne, Nicole Fiscella, Ricky Wilson, Dianne Vavra, Karl Giant, Anisha Lakhani, Susan Shin, Lara Lachman, Nell Rebowe, and Marilyn Muffs among others.
