#AMPtv just got the word straight from our TOP SECRET SOURCE in Nicki Minaj's camp that she has officially SIGNED THE CONTRACT to join American Idol.

According to our ROCK SOLID snitch, Nicki was all set to sign on - but ISSUES with her Pepsi endorsement were holding up the deal. But we OFFICIALLY LEARNED that as of yesterday - everything was worked out and Nicki SIGNED THE CONTRACT. So we know what you're wondering - how much does she get??? Our insider tells us that she's getting $8M up front. But get this . . . she has INCENTIVE FEES which kick in depending on the show's ratings. And if everything works out - Nicki will receive up to $18 MILLION for the season.
