The reality TV star says she now no longer spends as much time beautifying herself, although when she does, her baby daughter North is never far away.
"North actually will totally sit on my lap and is fascinated when I’m getting my hair blown out and when I'm getting my makeup done" Kim told Us. "I'll give her a little makeup brush, and she'll be entertained."
LA-born Kim says that since getting married to rapper Kanye West she has less time to work on her "secret weapon" – a glowing tan.
"I used to spray tan more before I got married," said Kim. "I would get it so dark and look so crazy.
"I don't really have as much time, so I just like to spray myself. The baby and husband are in bed sleeping, I spray myself and go to bed. No one wants to come in the middle of the night once everyone's down, so it just makes it easy."
Since expanding her family, Kim also no longer has as much time to enhance her tan naturally by sunbathing.
"I lay out a little bit," she said. "But, especially now that I have the baby, I don't have time. When she's napping, I do."
While Kim's daughter North is only one, the 33-year-old is already considering copying the way her own parents introduced her to make-up.
"I think it would be a good idea to get her a makeup lesson like we did," said Kim, alluding to a Christmas present her late father Robert Kardashian once gave her and her sisters.
"He said, 'If my girls are going to start wearing makeup, I want you to know how to wear it. I don't want you looking crazy.'"
