Scroll for the latest. The above photo landed on Chelsea's Instagram on November 7 – while pint-sized, Chelsea is definitely showing progress with her bump, today appearing in selfie mode and admitting: "Let's be honest" about living in sweatpants and leggings.

Chelsea's stories showed her in influencer mode for the South Dakota-based Lauribelles clothing brand she also has full-blown collections with.

"Boop!" Chelsea said while in a white distressed sweater and black leggings, also poking her bump – Chelsea also confirmed being a Medium, usually advertising her size as a Small.

"I'm only living in leggings and sweatpants," Chelsea said, also showing off her signature flame hair. "And also, I'm posting everything now," she added, then confirming it would all go live at 10 p.m. Central Time.

Chelsea, whose fourth baby is due in early 2021, hasn't just been making baby bump headlines, though.

Chelsea, who first found fame on MTV's "16 & Pregnant" as she welcomed eldest daughter Aubree with ex Adam Lind, is now confirmed to be exiting the franchise that made her famous. Earlier this month, the mom of three posed with 2016-married husband Cole DeBoer and her kids to confirm she's done.

"After much thought and discussion with my family and friends, Cole and I have decided that this season will be our last. We are forever thankful to MTV and our crew, who are like family to us," she wrote.

Chelsea, who is gearing up to launch her Aubree Says homeware brand – and it's got mad IG followers despite not yet retailing – added: "Our next chapter in life will focus on developing our brand and taking things to the next level with new endeavors and expanding family businesses."

Chelsea, already a partner with child and baby retailer Itzy Ritzy, also has a DIFF eyewear collab, plus she's the celebrity face of weight-loss brand Profile Nutrition – this, alongside influencing for HomeChef.
