And this afternoon Kim was obviously feeling pretty chuffed with her post-baby body, as she Instagrammed a picture of her naked stomach…three times in a row.
Kim has been stepping up her exercise regime ahead of her wedding, due to take place in France later this month.
And her hard work is shown to be paying off in the snap, where her defined ab muscles are clear to see.
At the weekend, Kim celebrated her very first Mother's Day with baby North West, sharing an adorable snap of the pair in black and white.
'This little girl has changed my world in more ways that I ever could have imagined! Being a mom is the most rewarding feeling in the world! Happy Mothers Day to all of the moms out there!' she wrote.
The bride to be is set to wed rapper Kanye West on May 24 in Paris, and reports are stating that they are putting £75,000 aside per guest.
The couple's invite was leaked online, although guests will not be told the exact location of the nuptials until the day itself.
