Capital FM have announced a stellar line-up for their Summertime Ball at Wembley on 21 June.

Miley Cyrus had already been announced on Wednesday morning and the singer was joined on the bill by 16 huge acts who were announced early on Thursday.

A number of the artists who helped make last year's event such a success will return including Sam Smith, Duke Dumont, Union J, Jessie J, Ed Sheeran and Ellie Goulding.

They will be joined by Cheryl Cole, Little Mix, Calvin Harris, Pharrell Williams, David Guetta, Clean Bandit, The Vamps, Rita Ora, Enrique Iglesias and 5 Seconds of Summer.

Wembley will become something of a home from home for Australian band 5 Seconds of Summer with the lads set to support One Direction at the stadium two weeks prior to the Summertime Ball
