Liv Tyler was the center of attention in Greenwich NYC last night. The gorgeous Lord of the Rings star arrived looking very chic in a black dress with a tailored black jacket, and her sweet smile echoed the innocence of her Givenchy adverts. As the cameras flashed, Liv and her pals modestly posed for the photographers before walking into the Waverly Inn. Everyone had joined Liv, to celebrate the Calvin Klein's Fall 2008 Collection's after party. Attendees included: Ali Larter, Kate Hudson, Julianne Moore, Helena Christensen, Molly Sims, Eric Dane and Rebecca Gayheart. Later Liv was seen leaving Ashton Kutcher's 30th birthday bash - it's just one party to the next for these celebrities! Pictures by Splash News / Edward Opinaldo
