First Check came across a reel on YouTube that features renowned American celebrities Kimberly Kardashian and Kylie Kristen Jenner, where they are talking about women’s appearance and the gender of the child that they are pregnant with.

The video is a short clip from the popular American reality TV show “Keeping Up with the Kardashians” and is at least two to three years old. It has more than 91,000 likes. In the video, Kim can be heard saying, “I think it’s a boy. You are skinnier this way. You are prettier than you were the last time. The girls take the beauty to give it to themselves. The boys know what’s up, and they just let you be a little bit prettier.”

Kim’s claim seems to reflect a playful take on a common pregnancy myth, suggesting that the person she’s addressing is pregnant with a boy, which she associates with looking “skinnier” and “prettier” compared to a past pregnancy. She implies that carrying a girl causes the baby to “take” the mother’s beauty, leading to less flattering physical changes, while a boy “knows what’s up” and allows the mother to retain or enhance her attractiveness.

Research suggests that a pregnant woman’s appearance, including weight gain, skin changes, or overall look, is influenced by factors such as genetics, hormonal fluctuations (e.g., increased estrogen and progesterone), diet, and individual health, not the baby’s gender.

A 2020 study shows that facial changes during pregnancy are driven by physiological factors unrelated to the fetus’s sex.

 Kim’s comment appears to be a playful, anecdotal remark, likely intended as a lighthearted compliment or conversation, rather than a factual assertion. The reel’s popularity highlights the cultural persistence of such myths, but they remain unsupported by scientific research.
