JAY-Z & MARY J. BLIGE HIT UP 10AK

The NY Post reports that club goers at 1Oak were treated to a replay of the sold-out Mary J. Blige and Jay-Z "Heart of the City" concert Friday night when the duo showed up to the West 17th Street spot and the DJ played snippets of their earlier performance at the Garden.

"It was so good, it sounded like they were performing," said one partier. "Everyone went crazy, Jay was rapping a little on the mike." Beyoncé later joined them at their table, where they hung out for hours.
