Kourtney Kardashian wants to give her half-sister Kylie Jenner a "super natural" make over.
The 37-year-old 'Keeping Up With the Kardashians' star has revealed her and her 19-year-old sibling are always talking about doing one another's make-up and filming it, and if it was to happen Kourtney would want to give Kylie a simplistic beauty look, whilst Kylie would do "heavy, crazy make-up" on her.
The brunette beauty told Marie Claire Online: "Kylie Jenner and I talk about doing each other's make-up all the time and filming it. I want to do it super natural on her and she wants to do some heavy, crazy make-up on me."
And Kourtney is positive Kylie, who built up her beauty empire Kylie Cosmetics over two years before launching her ever-growing beauty brand earlier this year, will love the chance of using her Lip Kits on her.

She added: "I'm sure she'd do a Kylie lip kit."
And the television personality - who is the oldest child in the Kardashian/Jenner brood - believes her and her siblings have "definitely" mastered the contour trend, and believes she has perfected the application of concealer under the eye, which she has claimed is "really hard" to do.

"I've mastered concealing under the eye too - it's really hard, not everyone can do it! The NARS concealer is great for under your eyes and for covering up spots."
Meanwhile, Kourtney has revealed she has found it harder to stay in shape after having three children, and because she doesn't want to miss out on spending time with her brood she undergoes gruelling one-hour workouts, which leave her feeling sick because they're so "intense".
Kourtney - who has sons Mason, six, and 23-month-old Reign, and daughters Penelope, six, with her former partner Scott Disick - said: "After each pregnancy it's been more difficult to stay in shape.
"Now if I take an hour to work out that's an hour away from my kids so I want it to be really intense - like I'm going to throw up!"
