The Teen Mom stars found out during a gender reveal party with their family and friends. "Today is the day! We finally get to find out if we will have a son or a daughter #Anticipation #IsKillingMe," Tyler posted on his Instagram page, along with this photo.
In the video from the party, Catelynn was wearing a pink "It's a Girl" ribbon, while Tyler was wearing a blue, "It's a Boy" one. Turns out, Catelynn was right!
The couple's first child was also a girl, but they made the difficult decision to give her up for adoption because they were too young and couldn't provide the kind of life they thought she deserved.
Now, Catelynn and Tyler are older, wiser and totally ready to be parents. We couldn't be more excited for them and can't wait to see pics of their baby girl when she's born this winter!
