It's only been one month since Kylie Jenner gave birth to her and Travis Scott's daughter, Stormi Webster, so you would be forgiven for thinking her body might not quite look how it did before she fell pregnant.

However you would be absolutely, 100% wrong. The Keeping Up With The Kardashians star has been posing up a storm in her undies, and all we have to say is woah.

Take a look at the video to see why Kylie Jenner is the ultimate saucy selfie queen...

The 20-year-old stripped down to a pair of black knickers and a crop top as she took to Snapchat to film her super flat stomach in the mirror.

Being sure to capture her literally amazing bod at all angles, Ky started off with a side view before moving on to a SITTING DOWN shot.

Yep, Kylie doesn't have even have a single roll sitting down, something we've tried and failed to achieve for as long as we can remember.

"one month," wrote Kylie, presumably referring to the fact that she looks like a living, breathing goddess just one month after giving birth to a child.

The snaps come after Kylie celebrated the milestone over on Instagram, where she decided to cover up and head outside with Stormi for an incredible mini photoshoot.

Kylie shouted out her 'angel baby' in the adorable pictures, writing: "my angel baby is 1 month old today."

One thing is for sure, Kylie is slaaaying.

Now take a look at the video to see Kylie Jenner's pregnancy and all the huge secrets celebrities tried to keep from us...
