Marc Jacobs threw Lorenzo Martone his 30th birthday party! It consisted of 150 friends at the nightclub, Avenue, which isn't open to the public. Julia Restoin Roitfeld, Modonna, Genevieve Jones, Larry Gagosian, Rachel Feinstein and John Currin were some of the guests who attended. The best part.. there was a cake in the shape of a bear. AWWWW the couple call each other BEAR...too cute!
