Khloé Kardashian's ''body vibes'' inspires Kanye West.

The 'Keeping Up With The Kardashians' beauty was asked by her brother-in-law to appear in his New York Fashion Week presentation, something she thought was a mix-up in the first place.

Recalling their conversation, she said: ''Kanye was like, 'I want you to come and be a fit model.

''And I was like, 'Did you mean to call Kylie [Jenner]?' And he was like, 'No, I'm calling you. Your body vibes are my influence this year.'''

And despite beating Kylie to be Kanye's muse, the 31-year-old beauty has admitted she's still envious of how the 17-year-old star and her 19-year-old sister Kendall eats.

She told Women's Health magazine: ''I'm not going to put on a bikini, sit on the floor with my legs crossed, and eat a burger.

''When I see my little sisters do that, I'm like, 'Ugh, these bitches.' I know they're not doing it on purpose. This is how they really eat and it's so annoying.''

Meanwhile, Khloé - who was known for her voluptuous figure - previously admitted she thought she was just ''big boned''.

She said: ''Looking back, I do believe I was unhealthy, but at the time I really thought that that was as skinny as I was going to get. You know, everyone's like, 'You're big boned.' I have childbearing hips.

''Even my producer ... who's been with me since Season 1 [of the family's E! reality show], which was nine years ago, she said, 'This is the best I've ever seen you look,' and it feels so good to finally like get to a place that I never even thought I could be.''
