A certain Teen Mom 2 feature is expanding her family tree: Chelsea Houska announced last night (July 12) that she and husband-to-be Cole DeBoer are expecting their first child together. Houska has one daughter, six-year-old Aubree, from a previous relationship with Adam Lind — the pregnancy and birth were first documented on MTV sister series 16 & Pregnant

"We are beyond excited for this journey and can’t wait to share it with you all!" Houska wrote on her website. "Big sister Aubree is also extremely excited and it’s no secret that she is hoping for a girl haha...I’m so grateful for everyone’s continued support and kind words!"

And fans were just as excited for Houska's new baby, which is due in February 2017 — many flooded Houska's teaser Instagram post with supportive sentiment.

"Ahhhh this makes me so happy!!! Congrats!!! Aubs looks precious," one wrote, while another noted "You deserve this, Chelsea! You and Cole are going to be the perfect parents and Aubree will be the best big sister! So happy for you all!!"

Houska and DeBoer first met at a gas station in 2014 and DeBoer has since been featured on Teen Mom 2. DeBoer eventually moved in with Houska before the couple adopted a pig named Pete together. DeBoer asked Houska to marry him in November 2015.
