The heavy hitters were out and about last night in celebration of Def Jam’s 25th Anniversary. OG founders Rick Rubin and Russell Simmons were guests at the event along with Jay-Z and some other notable names. Hov was spotted rocking a graphic T-shirt from Givenchy’s Spring 2012 collection. Shit is not even out yet! Looks like Tisci hooked him up while the rest of us have to wait (and pay) for the item. Must be nice.
