After promising a surprise in the lead up to their performance at the Wireless Festival, Jay-Z and JT did not fail to delight fans as Rihanna joined the pair on stage.

The singer could be heard before she appeared, joining Jay-Z to perform their 2009 number one single Run This Town. Sporting a new diamond grill on her teeth, her performance came towards the end of JT and Jay-Z’s two-and-a-half-hour set.

There were screams from the audience for Beyonce when Jay-Z started singing his 2003 collaboration with now wife, Bonnie and Clyde. However, fans were far from disappointed when it was the 25-year-old Bajan star that joined the boys on stage.

After opening with their number one single Holy Grail, the pair took it in turns to show off their much loved material including SexyBack, Mirrors and Encore.

The pair will be continuing their Legends of the Summer tour in New York’s The Bronx this Wednesday.
