It seems Nick Cannon knows his way into his wife Mariah Carey's heart for this Valentine's Day -- and that's Rice Krispie treats, gummi worms, Runts, and Now and Laters.

Nick bought the candy at the Renaissance Hotel's "Sweetest Suite" in New York City yesterday (2/10) - and that's not all. Mariah will be wowed when she walks into her hotel room and sees over 300 lbs. of candy provided by Dylan's Candy Bar!

I'm sure the couple will be enjoying an evening of edible gifts, but hopefully will have something to take care of of that sugar high.
