Wearing a floaty white dress and a large pink bow in her hair, fans could be forgiven for not immediately recognising this famous Keeping Up with the Kardashian star.
Nowadays she is no stranger to flashing the flesh and often proudly flaunts her curvaceous figure online.
In the sweet snap, the mother-of-three looks thrilled to be outside and happily smiles for the camera.
Kim, 37, also shared another picture with her 107,000,000 of her older sister Kourtney Kardashian, 38, cuddling her as a baby.
Donning a patterned jumpsuit and pink dolly shoes, Kourtney could be seen embracing her younger sister as they played around in what looked like a living room.
A much younger Kim wore a flower in her hair, which matched Kourtney’s and attempted to crawl while her sibling held onto her.
In another post, the businesswoman uploaded a short video of her first birthday cake.
The sugary desert had a large unicorn iced on and the word “Happy 1st Birthday Kimberly” written across it.
Kim, who welcomed her third child Chicago with husband Kanye West earlier this month, recently congratulated her younger sister Kylie Jenner on the birth of her first child.
The youngest member of the Kardashian Jenner clan gave birth to a baby girl on February 1.
Kylie, 20, had kept her entire pregnancy secret, but finally spilled the beans earlier this week.
On Twitter, she told her fans: “I’m sorry for keeping you in the dark through all the assumptions.
“I understand you’re used to me bringing you along on all my journeys. My pregnancy was one I chose not to do in front of the world.
“I knew for myself I needed to prepare for this role of a lifetime in the most positive, stress free and healthy way I knew how.”
Yesterday, the make-up mogul revealed that she and rapper boyfriend Travis Scott had named their daughter Stormi.
