Bumpin’ right along! Pregnant Teen Mom 2 star Chelsea Houska took to Instagram Sunday, December 11, to show off her growing baby bump.

The 25-year-old MTV personality shared a photo of herself posing with her friend Chelsey Grace while flaunting her belly in a skintight black dress. “Ummmm how hot is@cgrace13 ?! 😍🔥,” she captioned the snapshot. “Annnnnd how can this belly possibly get bigger 😬.”

Houska — who is expecting a boy with husband Cole DeBoer — treated fans to a glimpse of her baby bump for the first time back in October. The South Dakota native posted a snap of her bare tummy being nuzzled by her adorable pet pig, Pete. “Pete snuggling little baby 🐽 (my belly button looks extra weird from when I had it pierced😁),” she captioned the Instagram shot.

Prior to that, the 16 & Pregnant alum, who is already mom of Aubree, 7, with ex Adam Lind, uploaded a 3-D sonogram of her little one’s face via Instagram. “That FACE😍😍😍,” she wrote alongside the image. “Does baby look like mommy or daddy?!”

As previously reported, Houska and her fitness enthusiast hubby — who got married in an intimate wedding ceremony on October 1 — announced in July that they are expecting their first child together in February 2017.

"We are beyond excited for this journey and can't wait to share it with you all!" the second-time mom-to-be wrote on Instagram at the time. "Big sister Aubree is also extremely excited, and it's no secret that she is hoping for a girl haha."

Teen Mom 2 returns to MTV for its eighth season Monday, January 2, at 9 p.m. ET.
