Rihanna Secretly Sneaks Into Festival To Watch Jay-Z

They are known to be firm friends and have even collaborated with each other musically on multiple occasions. 

So it's no surprise that Rihanna, 29, made sure to stop by V Festival in Chelmsford, Essex, to see Jay-Z, 47, close the event with his headlining set on Sunday evening. 

Unbeknownst to fans, the Umbrella hit-maker managed to sneak into the festival and hide out backstage to watch her pal in action.
