Florence and The Machine have been named as the Friday night headliners for Bestival.
They join Stevie Wonder and New Order as the main acts this year.
Bestival takes between 6-9 September at the Robin Hill Country Park on the Isle of Wight.
The XX, Friendly Fires, Two Door Cinema Club, Orbital, Emeli Sande, Nero, Sigur Ros, Azealia Banks and Michael Kiwanuka have already been announced for the festival.
Miike Snow has also been added to the line-up.
A new performance area will also be in place at Bestival.
The Amphitheatre will be "nestled under a canopy of trees" and feature music, comedy, theatre and poetry.
Bestival was first held in 2004 and is organised by Radio 1 DJ Rob da Bank.
Every year they encourage festival-goers and the artists to dress up - this year the theme is wildlife.
In recent years it has seen themes like fantasy, space, rock stars, pop stars and divas.
