Kim Kardashian envies her 17-year-old sister Kendall Jenner’s slender figure because she finds it “a struggle” to lose weight.

Kim Kardashian wants to be her 17-year-old sister for one day.

The ‘Keeping Up with the Kardashians’ star admits she finds it a “struggle” to lose weight and is very envious of Kendall Jenner’s slender frame.

Asked which celebrity’s figure she most admires, she said: My little sister Kendall. I’m like, ‘I just want to be you for one day’. How are we even related?

“It’s a struggle for me [to lose weight], constantly.”

Kim’s boyfriend Kanye West recently gave her an image overhaul and cleared out her closet – but the brunette beauty admits she didn’t throw everything away immediately.

She told heat magazine: “You know, I kept all the clothes for about three months, sitting in a room with racks, just to see if I really was feeling it.

“And every piece I got rid of, I just felt like I had matured on my own.

“You know, it was probably a little bit harsh seeing it go. Now, I look back and I’m like, ‘I never would have worn that!’ So I’m glad that I got rid of everything and I filled my wardrobe up with really amazing pieces.”
