Not mad about mom jeans. Teen Mom 2s Chelsea Houska, who’s pregnant and expecting her first child with fiancé Cole DeBoer, recently took to Snapchat to show off her growing baby bump while rocking some maternity denim.

“I have a newfound love for maternity jeans,” the MTV personality, 24, wrote alongside a close-up of her growing belly dressed in stretchy, navy blue fabric.

Houska — who is also mom  Aubree, 6, whom she shares with ex Adam Lindannounced that she would be expanding her family with DeBoer via Instagram and her personal website on July 12.

“Oh my gosh! I’m so excited to finally be launching my website, and I felt like the perfect first post … would be to announce to everyone that baby DeBoer is expected in February 2017!” she wrote on her site. “We are beyond excited for this journey and can’t wait to share it with you all! Big sister Aubree is also extremely excited, and it’s no secret that she is hoping for a girl haha.”

Though she is ecstatic about welcoming another bundle of joy early next year, the 16 & Pregnant alum has admitted that she is feeling a bit anxious about becoming a second-time mom.

“I feel more nervous for some reason!” the South Dakota resident tweeted to fans on July 12. “It's been awhile and I want to do everything perfect #deboerbaby.”

Houska and DeBoer, whose relationship has been documented on TM2, began dating after meeting at a gas station in 2014. The fitness enthusiast proposed to the reality starlet in November 2015. The pair are planning to tie the knot this October.
