Blac Chyna has been giving fans a peek inside her pregnancy on her Snapchat account and recently took to the app to reveal exactly how much weight she’s gained since announcing her baby news. The model also posted several cute videos of her 3-year-old son, King Cairo, asking questions about his little brother or sister.

In one video, posted Saturday, Rob Kardashian’s fiancée decided to see how much she weighs. “Let’s see,” she said as she stepped on the bathroom scale. “Uh-oh! Mommy gained 20 pounds.”  In another video, Chyna’s son with ex Tyga quizzed her on if she’s having a boy or a girl, but she doesn’t answer. “I don’t know. What do you want it to be?” she asked him instead.

As previously reported, Chyna and Kardashian announced earlier this month that they were expecting their first child together. The news came just one month after they revealed they were engaged. Chyna and the 29-year-old sock designer have kept mostly quiet about her pregnancy, but it’s believed the 28-year-old model is due in the fall.

Recently, Chyna lashed out at fans for criticizing her pregnancy weight. According to Us Weekly, she took to Instagram posting: To all you people out here with negative comments and insecure words (obviously because you have nothing else to do but criticize the next) I AM HAVING A BABY! Exactly what do you expect to see? If I walked out in makeup and heels everyday to be beautiful to you means I WOULD BE MISERABLE AND UNHAPPY which are two vibes I refuse to transfer to my little one.”

Someone who doesn’t seem to mind Chyna’s curves is her soon-to-be husband. Kardashian posted a photo of the model wearing leggings and a crop top, writing, “My beautiful babies in Miami.” The “Keeping Up With the Kardashians” star also recently shared a video of Chyna showing off several bouquets of flowers. In the caption he wrote, “28 bouquets of flowers with 28 reasons why I Love Her for her 28th Bday! HAPPY BIRTHDAY ANGELA!! Awwww I’m the best! I LOVE YOU !!”
