The rapper has teamed up with his protégé Pepper for new track 'Scream', which will serve as one of five official hits to be used throughout the 2012 Games.
The pair have performed the track a handful of times since debuting it in full at last year's V Festival and have now premiered the studio version online.
The accompanying music video sees the duo performing the track during some festival dates, while scenes of Sylvester Stallone from the Rocky movies are interspersed throughout.
Dizzee Rascal signed Pepper to his Dirtee Skank record label after he found the star on Sky1's Must Be The Music, where he served as a judge.
Muse, Chemical Brothers, Elton John & Pnau and Delphic are the other four artists to supply official tracks for the London 2012 Olympic Games.
Dizzee Rascal's 'Scream' is available to pre-order now.
