Confirming that Marc Jacobs and Lorenzo Martone are the most sought-after couple in town, Jesus Luz and Madonna were among the 150 friends who came to the recent party Marc threw for his fiance's 30th birthday. At the not-yet-opened-to-the-public nightclub Avenue, guests (including Julia Restoin Roitfeld, Genevieve Jones, Larry Gagosian, Rachel Feinstein and John Currin) were treated to cocktails, sparklers and dancing, with music courtesy of Burberry's Alex Malgouyres. Luz even spent some time behind the turntable (we hear he's hoping to DJ as well as model). For the finale, there was a cake in the shape of a bear. Why a bear? It's a term of endearment the scruffily-bearded couple have for each other.
