Chelsea Houska knows how to raise a daughter -- and now the Teen Mom 2 cast member is going to learn how it compares to rearing a son. That's right: Chelsea and hubby Cole DeBoer are expecting a boy! A future "little Coley," to be exact.

"It's aaaaaaa.....BOY!," Chelsea captioned the adorable announcement above, with a cute ensemble for Baby DeBoer front and center. "Can't wait to add a little man to our crazy crew! @coledeboer."

Cole also added a snapshot from the gender reveal photoshoot and gushed about introducing "the most amazing man on the planet."

The sweethearts -- who said "I do" earlier this month and have been sharing a lot of sweet sonogram/belly updates throughout the pregnancy -- always planned to find out Baby DeBoer's gender before the munchkin was born. While big sis Aubree stated her preference was for another lady to join the brood, C-squared admitted they would be "fine with either." Bring on the blue -- and Aubs, you will love having a baby brother!

Be sure to stay with MTV News for more Baby DeBoer updates -- and share your moniker suggestions in the comments. And for a lighthearted rewind, watch Chelsea give pointers to all of the ladies out there searching for a guy just like hers:
