Blac Chyna and her fiancé Rob Kardashian confirmed they are expecting their first child together earlier this month.

On Saturday, May 21, the mom-to-be took to Snapchat to share the latest developments of her pregnancy — and turns out, there’s definitely something to report.

According to Dailymail, Blac Chyna was rattled to learn she had gained 20 pounds when she stepped on the scale with her 3-year-old son King Cairo, she had with her ex, Tyga.

The 28-year-old mum Snapchatted the weigh-in, exclaiming to King Cairo as the numbers 163.2 flashed onto the screen “Uh oh! Mommy gained 20 pounds.”

“Is it a boy or a girl?” King asks. She said: “I don’t know, what do you want it to be?” she asks back.

 The expectant mum’s relaxed attitude comes in contrast to her angry retort last week after critics body-shamed her for her weight gain.

She wrote: ”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!” she wrote on May 17 in response to mean comments on @thacelebriteanews Instagram account. “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.”
