Chelsea Houska's 4th baby bump just got a massive shout-out on Instagram – and it's getting big. The "Teen Mom 2" star is currently expecting her third girl and fourth overall child with 2016-married husband Cole DeBoer. Chelsea, 29, announced she was pregnant earlier this summer, with the reality star dropping the odd baby bump update for her 5.8 million followers since. Chelsea posted to her stories on Friday to show off the progress. Check out the mom of three's stunning shot below.

Scroll for the photo. The above one currently sits at over 800,000 likes on Chelsea's Instagram, where she's by far the most followed cast member – and she's gained 100,000 followers since dropping the pregnancy news.

Chelsea, already a mom to 11-year-old daughter Aubree, 3-year-old Watson, and 2-year-old Layne, posted a quick snap in her signature beanie hat today. The South Dakota-based star, wearing tight spandex leggings, had her growing bump swathed under a ripped and dark gray hoodie. Chelsea posed smiling with closed eyes, then writing: "Bump friendly for the WIN @shoplilyandlottie."

Keep scrolling for more photos. Chelsea's pregnancy announcement came pretty unusual – no sonogram for this redhead as she posted a photo of a wood-panel doorway with her household's names written on it: "Cole, Chelsea, Aubree, Watson Layne," she wrote, then adding: "Baby" with a heart emoji. "One more DeBoer," Chelsea captioned the photo, confirming her fourth child is due in 2021.

Chelsea has since snagged herself 1 million likes for her gender reveal photo: "Baby.....GIRL!!!!" she wrote.

Chelsea also waited to announce her news after "Teen Mom 2" co-star Kailyn Lowry confirmed she'd safely welcomed fourth son Creed. More below.

Chelsea is earning her cash big-time these days, and fans largely feel she's got a good business mind. The star has full-blown collections with the Lauribelles clothing brand she influences for, also continuing her 2019-launched Itzy Ritzy collab with hunky husband Cole. Chelsea is also the celebrity face of weight-loss brand Profile Sanford, crediting the diet plans for her 50-pound drop after welcoming youngest Layne.

To top it all off, Chelsea influences for Home Chef where she shares her easy-to-prepare meals. She's also had an eyewear collab with DIFF.

Chelsea is fresh from looking back at around a decade of filming on the hit MTV franchise. In August, the star took to social media, writing:

“Ten years, one husband and two more kids later … @ChelseaHouska’s dreams have all come true,” the Teen Mom Twitter captioned the footage. Sharing it on her own page, Chelsea, 28, added, “Seeing this knowing what I know now … makes my heart ache. What a journey it’s been.”

Chelsea shot to fame on MTV's "16 & Pregnant" before becoming a core member of "Teen Mom 2."
