The pair are the latest acts to be confirmed for the festival, which will take place on London's Hackney Marshes over the weekend of June 23-24.
Lostprophets, B.o.B, Ben Howard, Delilah and Enter Shikari will also perform at the event.
They join a long list of acts already on the bill, including Jay-Z, Jessie J, Lana Del Rey, will.i.am and Leona Lewis.
Registration for the 100,000 free tickets available is open now and closes on March 19. People who have registered will then have two opportunities to apply for tickets on March 25 and March 26.
Although tickets are free, a small charge of £2.50 per ticket will be required to cover handling and administration costs.
