Kim Kardashian shows off tiny waist while hard at work ... doing what?
We aren't sure exactly what she's working on, as the reality starlet is mum as to what project the photo is from. We would guess it's some kind of photoshoot for one of her many products -- perfume, makeup, Kardashian clothing line, etc.
The whole Kardashian family was busy recently celebrating Kendall Jenner's 18th birthday. They rented out Magic Mountain and Kim tweeted this adorable picture, wishing Kendall, "Happy 18th Birthday to the sweetest girl I know @kendalljenner I hope your adult years are filled with happiness & so much [heart emoji]."
