And the source claims Carey is keen to keep the romance under wraps: "Mariah is the master when it comes to keeping her relationships secret. Even though she's a big star, she likes to keep her private life to herself."

Carey's exes include record boss Tommy Mottola, rapper Eminem and singer Luis Miguel. Cannon was last known to be dating actress Zulay Henao, after breaking off his engagement to model Selita Ebanks.
