Meanwhile, his homie Nas rocked out in Manhattan at Radio City Music Hall with Elle Varner.  Pics inside...


Jay-Z put on his tux for a dapper night of music at the home of the Brooklyn Nets, the Barclays Center.  And he asked Chris Martin, his wife Gwyneth Paltrow and their kids come on stage at the stroke of midnight to dance around on stage.

Nas made his way to his show with his daughter Destiny.
Opener Elle Varner tweeted pics of her and Mr. Jones' sexy self before the show.

She looked fab in a silver mesh and sparkling dress as she kicked it with her friends after the concert.  Fab times.
