To celebrate the launch of their Os Gemeos limited-edition bottle, Hennessy staged a baller warehouse bash on Pier 57 last night. The twins themselves DJd the party from a futuristic mirrored cube, which was then dismantled to make room for a live set by Nas, to ensure things got totally bananas. DJ Jazzy Jeff (yes, that one) and a copious selection of cognac and Brazilian bites warmed up the crowd, which included Rocky and the A$AP Mob, who rolled through to catch Nas.
