Justin Timberlake and Jay-Z are to headline this summer's Wireless Festival as it moves to its new home at the Olympic Park in east London.
Sexyback singer Justin, making his musical comeback after a spell of acting in films such as The Social Network, will be playing his only UK festival performance of the year.
Rapper Jay-Z will be playing his only UK date when he performs at the Queen Elizabeth Olympic Park in July.
Also on the bill for the July 12 and 13 shows - which formerly took place in London's Hyde Park - will be Snoop Dogg, Frank Ocean, Rita Ora and Calvin Harris. Emeli Sande will also be returning to the Olympics site, where she memorably performed at the opening and closing ceremonies.
A new festival is to be staged in Hyde Park, the Barclaycard British Summer Time, after a change of promoter.
Tickets for Wireless go on sale on Friday February 22.
