Chelsea Houska just hinted that she and Cole DeBoer are expecting a baby girl. Although the Teen Mom 2 star has not yet officially confirmed the gender of her second child, the first for DeBoer, fans are now convinced that Houska's oldest daughter, Aubree, will soon be welcoming a baby sister.According to a September 7 report by In Touch Weekly magazine, Houska was recently caught pinning baby girl outfits on Pinterest. As the magazine revealed, Houska pinned an adorable pink floral romper and a cute onesie, which read, "I Love Daddy Dearly."

While Chelsea Houska's recent pins may not have meant much if she didn't know what the child's gender was, she already knows what she's having.

Although the Teen Mom 2 star has kept the news to herself for weeks, she revealed last month that she and DeBoer are aware of their baby's gender.

Chelsea Houska's daughter has a younger sibling already

Three years ago, Houska's daughter, Aubree, became a big sister for the first time when her father, Adam Lind, welcomed his second child with his then-girlfriend, Taylor Halbur. And while the couple split just months later, Lind sees Paislee regularly and often, he has both of his girls at the same time.

In her official baby announcement in July, which was shared on her official website, Chelsea Houska revealed that her daughter was hoping for another little sister as she and DeBoer prepared to welcome a child together.

She also said that Aubree was making it quite clear that she was not willing to be the big sister of just any sibling.

Chelsea Houska is getting married in the coming weeks

Houska has stayed mum on her official wedding date, but she did recently say that she would be celebrating her marriage to DeBoer in the fall. She also told her fans on Twitter that she would be a pregnant bride as she and DeBoer had no interest in postponing their ceremony until after their baby is born.

Chelsea Houska and Cole DeBoer are currently in production on the upcoming season of Teen Mom 2. No word yet on when the series will return to MTV.
