The Kardashian sisters have never been shy -- especially when it comes to showing off their bodies.
And why should they be? They have gorgeous curves and they might as well flaunt them.
Kourtney Kardashian is here to prove age is just a number, and it's definitely not slowing her down. The mother of three turned 38 in April and celebrated by going on a vacation with her girlfriends and sister Kim.
But before she jetted off on her birthday trip, which honestly looked more like a bachelorette party or extremely luxurious spring break than a girls' getaway, the oldest Kardashian stripped down for a completely naked photo shoot.
Yeah, it was sexy AF.
Kourtney teased the internet with her "birthday suit" a few weeks back, but if you thought that's all we were going to get from the reality star, you clearly don't keep up.
In a new promo for "Keeping Up with the Kardashians," we get to go behind-the-scenes of the nude photo shoot and see Kourt strip down as Kylie, Khloé and Kim watch on with approval.
In the clip, Kourtney comes out by the pool in a robe, and it seems like even her sisters might underestimate her confidence. Kylie asks, "So you really are getting naked?"
Kourtney, taken aback, replies, "Yes! What do you mean?"
Kourtney doesn't hesitate before stripping down and posing alongside the pool.
Then, she gets in the pool and things start to really heat up.
Meanwhile, Khloé, Kim and Kylie cheer and catcall from behind the camera.
In fact, 19-year-old Kylie even gets a bit jealous of her big sis.
Khloé, on the other hand, is bursting with pride.
During the "KUWTK" interview, Khloé says to Kourtney,
I honestly was worried about you after Penelope. I did think, like, 'She's gone'... now she's yolo-ing it up, bomb-ass body, naked in the pool and your sisters should be afraid of you.
I don't know about her sisters, but I'd love to know what Scott Disick thinks of all this.
Disick is rumored to be dating a 21-year-old model (Kourtney is also apparently dating a much younger model), but I have a hard time believing his ex, and mother to his three children, has lost one moment of sleep over his fling.
Yep, it look like Kourtney is doing just fine at 38.
