Wearing a figure-hugging black dress, the model showed off her blossoming new curves with a bathroom mirror snap.
Captioning the image "Somebody is early to the party", Chrissy revealed a cute, small bump.
Fans were quick to comment on her "beautiful" snap, however, unfortunately not everyone was expressing excitement. Yep, there were some internet trolls around who took it upon themselves to criticise Chrissy's shape.
This slew of unwarranted comments led to the 29-year-old swearing off baby bump updates altogether. Chrissy wrote in a Twitter post: "No more preg tweeting for me, lesson learned!! Back to food and reality TV and hay things."
As much as we love drooling over Chrissy's food snaps, we really hope this isn't the case!
Last week (12 October), Chrissy revealed herself and husband John Legend are set to become parents for the first time, announcing their exciting baby news on Instagram.
Sharing a snap of the two of them, Chrissy told fans: "John and I are so happy to announce that we are pregnant :)."
The couple's baby news has been a long time coming for the pair, who have spoken in the past about their struggle to conceive.
Chrissy added in her post: "As many of you know, we've been trying to have a baby for a while now. It hasn't been easy, but we kept trying because we can't wait to bring our first child into the world and grow our family.
"We're so excited that it's finally happening. Thank you for all your love and well wishes. I look forward to all the belly touching! Xx."
John, meanwhile, made sure to share their news on his own social media accounts, simply tweeting: "We're pregnant!"
John and Chrissy's baby joy comes two years after they wed in Como, Italy.
So far Chrissy is yet to announce how far into her pregnancy she is or their unborn baby's sex.
