Chelsea Houska recently stated that she couldn't wait to have “little Coleys” with her fiancé Cole DeBoer — and now the lovable Teen Mom 2 couple is one step closer to that exciting, life-changing moment. That's right, the MTV sweethearts are having a baby!

"And then there were four..." Aubree's mama captioned the announcement photo above with a link to her new website, while Cole shared the same heartwarming image and added "couldn't have asked for a better blessing!"

"We're really excited and Aubree is pumped to be a big sister," Chelsea exclusively told MTV News, while Cole stated "I'm a proud dad of one already, so adding another to the family is just amazing."

A brief relationship recap: Chelsea and Cole met at a gas station and started dating in August 2014. Before long, he made his debut on the long-running program and viewers got to watch their love story flourish. From there, they welcomed their first addition together (pet pig Pete!) and, soon after, Cole moved in with his girlfriend and her mini-me. He sweetly asked for Chelsea's hand in marriage — with Aubree in tow — back in November 2015, and the rest is history!
