On September 17, the Kardashians star posted on Instagram a behind-the-scenes 

photo from her recent photo shoot for a campaign by supplement brand Lemme. She was 

wearing a nude bra and matching panties, which appear to be 

from her sister Kim Kardashian's brand, SKIMS. In one of the clips, she puts her hand .

on top of her belly, which generated some comments about pregnancy

"Wait a minute," said one person, "she's pregnant and I don't know?"

Kourtney replied, "No, but you are failing to recognize a woman's real body."

In the comments, several fans praised the Poosh founder's look, including her sister Khloé Kardashian, who wrote, "You are amazing."
