Kourtney Kardashian has evidently been working hard to get back in shape following the birth of her third child — and she wanted to share her weight loss with fans.

But the Instagram photo the 5-foot-tall reality star posted on Friday of her scale, which showed that she was down to 120 pounds, garnered mixed reviews.

"First day that I have seen this number in a while," Kardashian, 35, captioned the image.

Comments on the post were divided, with some followers criticizing the number on the scale as too low, and others jumping to Kardashian's defense.

"It is ridiculous that you think it's appropriate to post this when there's people who have eating disorders and body issues," replied one.

"You go girl!!" cheered another woman, while a third proclaimed: "Good healthy weight. Congratulations!"

Kardashian welcomed Reign Aston Disick on December 22. She and Scott Disick are also parents to Mason, 5, and Penelope, 2.

The celebrity mom hasn't been shy about showing off her fit physique. Two weeks ago, she shared a throwback bikini photo of herself on Instagram, taken one year after Mason's birth.

"Just found this pic and now I'm going on a run! This was in Bora Bora when Mason was a year old," she wrote.
