Fresh from stealing the show at this month's Grammy Awards, Nicki Minaj will join Saturday 7 July's line-up as Drake's special guest. A massive worldwide superstar, she is currently riding high in the UK charts with her new track Spaceships. She'll be joined on the day by a host of new additions, including X Factor judge and N-Dubz singer Tulisa, dubstep maestros Nero, the brilliant Knife Party (founded by Pendulum's Rob Swire and Gareth McGrillen) and London based Nigerian popstar D'banj.
