Reality star Khloe, 31, stripped down for the new issue of the mag, baring all in a gym-themed shoot to show off the results of her intensive daily workouts.
And big sis Kim is impressed!
Kim, 34, said: "Khloe was always so hesitant about doing a sexy shoot just out of fear but she conquered her fears and went for it! I'm so proud of her!"
The pregnant star added of her sister: "How good does she look? DAMN! Obsessed with this hoot! Hard work pays off!"
Of course, Kim's no stranger to a sexy shoot herself, famously stripping off completely stark naked for Paper magazine last year. (And we mean fully stark naked!)
We wonder if she gave Khloe any advice?!
Fellow sister Kourtney, 36, also gave Khloe's shoot a shout out, wrting on Instagram: "WHAT?!!!!!! @khloekardashian on the cover of Complex looking [hot]. #mondaymotivation."
Why is Khloe famous?
