EXCLUSIVETyga's former manager says the rapper's an ingrate and now there's only one way to show his appreciation ... fork over several million dollars as a "thank you."
Back in the day ... Tyga hired C&J Management, and the company claims it did more than a good job, "turning him from a relative nobody to a world known superstar." C&J introduced Tyga to Cash Money, so they may have a point.
But sometimes people and Tygas move on ... and C&J claims the rapper unceremoniously and illegally fired them in 2013 and hired a brand spankin' new manager.
So C&J now wants $4 million and all will be well.
We reached out to a rep for Tyga. So far, no word back.
