The 31-year-old socialite went public with her new love earlier this year, following her split from sportsman husband Kris Humphries shortly after their wedding last summer.
Kardashian has been friends with the rapper for several years and she said that their strong connection provides a solid base for romance, reported InStyle magazine online.
"We know what we are to each other. We've had a deep friendship for so long and that's the start of a really good relationship," she said.
Kardashian also dismissed rumours that West has been writing about their romance in his songs.
"People can interpret it however they want. That's him making music. I don't even know it's about me," she added.
