Khloe Kardashian is being slammed over this workout video...

Khloe Kardashian has just been mummy-shamed for the first time.

The 'Keeping Up With The Kardashians' star, who recently revealed she's six months pregnant, took part in a gruelling home workout alongside her sister Kourtney.

And while it's no secret the reality star loves to work up a sweat, people were not happy when Khloe uploaded a video of her intense workout on Snapchat.

Fans were quick to attack 33-year-old, suggesting that she shouldn't be exercising this far into her pregnancy.

But Khloe was not having a bar of it.

Taking to Twitter, she shared an article from fitpregnancy.com with the title '33 reasons to exercise now'.

With the article she wrote: "For the ones who think they are physicians all of a sudden. But MY doctor and I communicate and my workouts are cleared and highly recommended. Thanks kiddos! Don't make me stop sharing s**t."
