Rihanna Gets 'LOUD' with Jay-Z at New Jersey Show [Video]

The Roc was in the building at Rihanna’s “LOUD” tour stop in New Jersey on Thursday night (July 21). Fans were in for a surprise when Jay-Z joined the red-headed superstar during the encore at East Rutherford’s Izod Center.

RiRi threw up the diamond before her mentor emerged in a cloud of smoke from below the stage rocking camouflage shorts, a Basquiat T-shirt, and a snapback Yankees hat. The crowd went wild as he performed his verses from “Run This Town” and “Umbrella” with the pop princess.
