Baby DeBoer is almost here! Chelsea Houska shared a sweet clip of her lil' bump over the weekend — and it's so stinkin' cute. The Teen Mom 2 star took to Instagram stories wearing a white and blue striped swimsuit — but unfortunately, her day didn't go as planned! Watch the video above for all the deets.

Just last week, fans thought the 26-year-old casually revealed the name of her third child on Instagram, but it turned out to be a misunderstanding. "Making @tm.pi and baby Willow a treat," she shared. Immediately following the snap, Chels took to Twitter to clear up the confusion. "My friend just had a baby, named Willow. And we are going to meet her today," she explained. When a fan shared a similar experience, she said, "Lolllll ugh!!! I can't even say my friends kids names anymore I guess!"

Chelsea and her husband, Cole DeBoer, first revealed that they were adding a third baby to their brood in March. "….GUESS WHAT! A sweet baby girl will be joining the DeBoer clan in a few short months!" the MTV personality captioned a photo of her ultrasound. "We could not be more excited!" Cole shared the same photo and gushed, This proud dad is getting a new Bow and it's nailed my heart."

Chels — who shares Aubree, 8, with her ex Adam Lind and Watson, 1, with Cole — said her daughter is thrilled about having another girl in the house. "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!" Chelsea told MTV News after revealing her pregnancy. Her husband joked, "The men in this household are standing their ground even though we are outnumbered." We can't wait to meet their little one in September!
