The 38-year-old proved she looks just as good naked as her sister Kim as she shed her clothes for one of her most jaw-dropping photos ever.

Posing completely in the nude in the tantalising snap, the mother-of-three perched on a rock surrounded by greenery.

As Kourtney turned to the camera to give a smouldering look, she flashed plenty of sideboob.

The stunner’s peachy posterior would have also sent her followers into a frenzy as it was on full display in the eye-popping photo.

If it wasn’t for the reality star’s strategically placed arms, the brunette beauty would have completely exposed everything to her fans.

Kourtney captioned the totally starkers post: "Fitness week, on my app.”

And it didn’t take long for her 60million Instagram followers to compliment the petite stunner with one person gushing: “Gorgeous is an understatement.”

Another person praised: "So hot and sexy," whilst a third simply stated: "My favourite Kardashian."

Kourtney first shared the nude snap in May last year after she took part in an exotic photoshoot in Costa Rica.

The gorgeous star re-posted the picture just days after her sister Kim attempted to break the internet once again.

Last week, the 36-year-old curvaceous beauty posed virtually nude as she stripped down to just a white thong while she relaxed in bed.
