The 42-year-old rapper was joined by Rihanna who was decked out in a white and tan suit.
Along with the grand opening, Jay-Z is also planning a stint of performances at his new hot spot.
“I really hope it’s just a celebration,” the new father told MTV. “Pretty much all the concerts are loud and sing-a-longs, but I hope that this is a special thing. It’s pretty much a celebration of having a team in Brooklyn — you know, again, everybody knows we hadn’t had a team since the Dodgers, so it’s really a happy time in Brooklyn.”/celebrity-gossip.net
