It looks likes another MTV brood is about to become a little bit bigger!

On March 15, Teen Mom 2 star Chelsea Houska, 26, and husband Cole DeBoer, 29 took to Instagram to announce they're expecting another child.

The couple welcomed their son Watson Cole in January 2017, and Houska also has an eight-year-old daughter Aubree Lind, who was born on her episode of 16 and Pregnant.

"Aubree did such a great job keeping this a secret and she said at school on Monday she's gonna walk in and start yelling it down the hallways!" Houska told MTV News.

In a Teen Mom 2 episode aired last August, Houska opened up to a friend about expanding her family.

"We have baby fever already," she said. "I just want so many baby Coles. I think it'd just be fun to have so many babies closer together."

"Aubree ... it was seven years before we had another kid," Houska added, speaking about the age gap between her two children. "We need to just be patient, but I can't help it."

Luckily, the reality star's wish would come true, and the couple have already revealed the baby's gender.

In an Instagram post, Houska announced she and her husband are expecting a baby girl, along with a picture of the ultrasound.

"....GUESS WHAT! A sweet baby girl will be joining the DeBoer clan in a few short months! We could not be more excited!" she wrote on the social networking app.

DeBoer would soon post the same picture, captioning it: "This proud dad is getting a new Bow and it's nailed my heart."

While Houska's due date hasn't been revealed, she said DeBoer is "very excited" and "talks to my belly every night."

"I'm ecstatic to have another princess under our roof," he told MTV News. "The men in this household are standing their ground even though we are now outnumbered."

What do you think the couple will name their little bundle of joy?
