She said on "The Ellen DeGeneres Show" last week that she and her beau had low-key plans for Valentine's Day.
"He actually has a game on Valentine's Day so I will be with him after the game. I'll probably cook dinner and having food waiting for him when he comes home. Maybe look a little sexy," she told DeGeneres.

"I actually love Cleveland. Everyone is so nice there," she added. "I love routine. It's a normal, routine life. I love to cook, so I get to cook dinner every day. It's, like, this home, family thing that I've been craving."
Kardashian finalized her divorce from Lamar Odom in December after initially splitting from the former NBA player in 2013.
