The 41-year-old star feels it is important to have heart in the wedding and rest does not mater, reported The People magazine.
"I just want to show up. I have Lee Press-On Nails. I'm not that kind of girl. I don't care, as long as the heart is in the ceremony, that's all that matters to me. I could get married in a Kentucky Fried Chicken (KFC)," she said.
The model said she has decided on a black-and-white theme for the wedding, similar to the one Kim Kardashian-Kanye West chose for their big day.
McCarthy previously dated Jim Carrey.
