Kim Kardashian's
training for her big day ... literally! 

The "Keeping Up with the Kardashians" star showed off her tight tummy via Instagram on Tuesday. 

Rocking just a spots bra in the shot, the mother-of-one's abs are on full display. "Just finished my morning workout," she captioned the sexy snap. 

Sources tell TMZ that Kim and Kanye West's wedding will take place in Paris, France over Memorial Day weekend -- so, we're sure the reality star's trying to be in the best shape possible for her trip down the aisle. 

And for giving birth less than a year ago, Kim looks pretty amazing! What do you think of North West's mom's latest candid? 

It's pretty similar to one younger sister Kylie shared just yesterday, where she also shows off her tight tummy.
