Major Lazer and Mary J. Blige have been added to the Wireless Festival line-up.

Diplo's side project and the 'Family Affair' singer will both perform at the three-day festival in London's Finsbury Park along with the previously announced headliners Drake, Avicii and David Guetta.

Other new additions to the line-up include Belgian singer-songwriter Stromae, rising star PARTYNEXTDOOR, drum and bass producer Netsky and 21-year-old '2 On' hitmaker Tinashe.

Hip hop star Pusha T, brothers Rae Sremmund and reggae musician Collie Buddz will also perform at the event which runs from July 3-5.

As well as the latest act announcement, organisers of the festival have teased a special guest for the opening evening of the festival, who will take to the main stage between Canadian rapper Drake and the already-announced Major Lazer.

The 2015 event will be the tenth anniversary of the festival - which is sponsored by fashion retailer New Look - with other acts including Nicki Minaj, Jessie J, Kendrick Lamar and Labrinth set to perform.
