According to the duo's official site they will play at this year's Glastonbury Festival.
Details of which stage they will play are yet to be announced.
The Chemicals join Paul McCartney as self-confirmed acts at this year’s festival, of course the organisers keep the official line-up close to their chests until the weeks leading up to the event.
So far other rumoured acts include James Brown, The Strokes, Oasis and The Cure.
The Chemical Brothers will also play Ireland’s Oxegen Festival and Scotland’s T in The Park this summer.
Glastonbury 04 takes place 25 June to 27 June at Worthy Farm, Pilton.
