Jay-Z & Justin Timberlake Perform “Holy Grail” Live For The First Time, Rihanna Joins Hov: Watch

Jay-Z and Justin Timberlake closed out the UK’s Yahoo! Wireless Festival with a joint set on Sunday night (July 14), but before kicking off the Legends of the Summer tour, they each had a solo headlining set at the fest (JT on Friday, Jay on Saturday). Hov during his set brought out JT for Magna Carta Holy Grail opener “Holy Grail” (the previous night, Jay joined Timberlake for “Suit & Tie”). Wearing a suit and baseball cap, JT belted out the opening bars, and the crowd went bananas once the beat dropped in. Check that out up top.

On Sunday during the Jay-JT joint session, Hov had one last surprise for the British crowd, as Rihanna made a guest appearance for “Run This Town” (sans Kanye West). Watch that performance below.
