The X Factor and America's Got Talent creator was planning to put together a new show to find the next big Djs, but the project was eventually scrapped last year (12).
Fatboy Slim has now revealed he was approached about joining the show, but he was determined not to take part.
He tells Britain's The Sun, "As dance music gets taken over by people like Cowell it becomes about being famous and money, the nasty side which I think for years it was relatively free of. Kids grow up thinking to be a Dj, you've got to be sexy and bling... it's not about that. I'm glad that's one bandwagon he didn't jump on."
He goes on to urge Cowell not to revive the project, adding, "Please don't do it, it'll ruin it for the rest of us."
