Mike Skinner is penning the score for the Inbetweeners movie, according to reports.
The Streets star is a huge fan of the show and jumped at the chance to be involved in the film, The Sun said.
A source told the newspaper the singer-songwriter was first choice, saying: "Mike is the perfect fit. All the material he is writing for the film is new. He is really excited about the whole thing."
The film, produced by Film4, will see the boys travel to Malia, Crete on a lads' holiday to celebrate finishing their A-Levels before going off to uni.
Joe Thomas, who plays lovelorn Simon in the E4 comedy, has said of the film: "It's funny, it's the sort of holiday I did everything in my power to avoid going on when I was in the final year of my exams. But yeah, it's kind of a mental, messy holiday."
Mike recently called time on The Streets with a farewell tour.
