Kris Humphries Won't Try Wedding Cake for Kim Kardashian: "I Don't Eat Sweets"

The world is about to get an inside look at the celebrity wedding of the year between Kim Kardashian and Kris Humphries. Kim's Fairytale Wedding: A Kardashian Event airs Sunday, and E! has released an exclusive sneak peek of the bride and groom prepping for their big day.

The clip shows that Kim and Kris have a lot to learn about one another before heading down the aisle.

During a family wedding cake tasting outing, Kim urges Kris to help her choose a cake flavor, but Kris refuses.

"I don't eat sweets," he says, as Kim dives into the different flavors.

Even momager Kris Jenner can't understand this.
