The 30-year-old reality star opened up to US magazine Self about her obsession with cleanliness.
She said: 'I'm just the biggest neat freak at home. I don't have people over for that reason, because I don't like anyone in my space.
'I think I was a housekeeper in my last life. Sitting at home in sweats and cleaning out my closet would be a perfect night for me.'
And The Keeping Up With The Kardashians star, who appears on the cover of the April issue of the magazine, also revealed that she is equally dedicated to looking after her body.
She said: 'Everyone has the power to make good decisions, whether it is about your career or fitness routine. As long as you stay dedicated to something, you'll see a change. If you are committed, you can do anything!”
She added: 'Find the one part of your body that you love and accentuate it. For example, because I have a small waist, a big butt and thin legs, belts work for me. You have to know what looks best on your body.'
