The 60s rock band will reportedly join 'Bound 2' rapper Kanye West and the Foo Fighters as headliners of the music festival, which takes place in June, reported Daily Mirror.
"The Who booking has been kept quiet because the band are also playing a Hyde Park gig for the British Summer Time festival so the announcement will be made in a few weeks," a source said.
"The band are still one of the best live groups and are currently on their 50th-anniversary tour, so it's bound to be an amazing show.
