Rihanna thrilled gig-goers at her show in New Jersey on Thursday night (21Jul11) by performing with her mentor Jay-Z.
The Bajan beauty put on a concert at the Izod Center in East Rutherford, New Jersey and she opened her encore with an appearance from the hip-hop giant, who emerged from beneath the stage on a circular platform.
Jay-Z then launched into collaborative track Run This Town, before joining Rihanna on her chart-topping Umbrella, according to The Star-Ledger.
