Justin Timberlake and Jay-Z will preview their upcoming collaborative US tour by performing together on the final night of this year's Wireless Festival.

The pair are already confirmed to independently headline a night each at the festival, which is taking place at London's Olympic Park in July.

The 'Mirrors' star is topping the bill on Friday July 12 and Jay-Z is performing a day later on July 13 - but they are now set to hit the stage together on Sunday July 14.

It comes as a special preview of their Legends of the Summer US tour, which is taking place in stadiums across the States later this year.

Other names to have been added to Wireless meanwhile include Ke$ha, A Tribe Called Quest, Wretch 32, Nas, A$AP Rocky and Rizzle Kicks.
