Before the Grammys were in full swing on Sunday night, Jay Z and his Roc Nation team hosted a star studded pre-party at a private location in Beverly Hills. Presented by MAC Viva Glam, the soiree was filled with some of the biggest names in entertainment, including Rihanna, Rita Ora, T.I., and Kevin Hart. 

Jay Z looked dapper in a black suit as he puffed on a cigar and made his way around to mingle with his celebrity friends. Rapper J. Cole was spotted in the crowd, as he made his way over to the cigar station, where other Roc Nation power players were posted up.
