Rapper/actor Nick Cannon has laughed off rumors his marriage to Mariah Carey is on the rocks, insisting they couldn't be happier.

The couple wed in the Bahamas in April after a whirlwind romance, but earlier this week internet gossips were already speculating about trouble in their relationship.

Reports alleged that Cannon was tiring of the R+B superstar's demands, with one source telling Ok! magazine, "He's basically around to attend to her diva-ish ways."

But Cannon has dismissed the claims.

He tells People.com, "Marriage is amazing. It's the best thing that ever happened to me."
