The star will release The Origin of Love as his third studio album later this year and has unveiled the accompanying artwork.
The cover sees a black and white headshot of the singer wearing a crown of thorns that is made out of golden liquid.
'Celebrate' serves as the collection's lead single and was co-written by Mika, Pharrell Williams and frYars.
"This collective and open attitude was at the heart of The Origin of Love. It's an album about crazy love songs and tolerance. It was recorded in Miami and London but mostly in frYars's north London bedroom studio," Mika explained.
Mika has also worked with William Orbit, Benny Benassi, Greg Wells (Katy Perry, Adele) and Klas Ahlund (Robyn's Body Talk) on the record.
