Yahoo! Wireless Festival has announced that it will be extended into a third day.
Organisers have confirmed Justin Timberlake and Jay-Z, who were previously confirmed for the festival, will now also headline the event on Sunday 14 July.
The pair will use the new date to preview their upcoming Legends of the Summer US tour which makes us feel pretty special that they'll be doing to gig in the UK first!
A Tribe Called Quest will give their first UK performance in 20 years on the Sunday as well as rapper Nas, A$AP Rocky and Rizzle Kicks.
Justin will headline the festival on Friday 12 July and Ke$sha, Wreth 32, Comor Maynard, Bingo Players and Iggy Azalea have been added to the bill.
Meanwhile, Macklemore and Ryan Lewis, Zedd and Flux Pavilion will join the bill on Jay-Z's headlining Saturday.
This year's Wireless Festival is the first to take place at the Queen Elizabeth Olympic Park in Stratford, East London, following the event's relocation from Hyde Park.
Tickets for the new date go on sale at 9am on 15 March 2013 and start from £75 (excluding booking fees).
