We have the best year to look forward to and this has just made it extra special.''
James King, Senior Vice President of AEG Live, added: ''We're super excited to be announcing Green Day as our first headliner for 2017. So many hits and also some amazing new music as well.
''London is going to be treated to one of the best stadium bands of our generation on the Great Oak Stage in Hyde Park.''
