Tyler and Catelynn are expecting their second child together and revealed they are having another daughter in a cute Instagram video this weekend.

Alongside the video, Catelynn commented: "It's a........."
Last week, following much speculation, Catelynn and Tyler revealed they were expecting a baby together five years after giving up their daughter, Carly, for adoption.
The couple had welcomed Carly into the world when they were just 16 and admirably made the decision to have her adopted, as they felt she would have a better life than the one they could give her.
MTV's 16 and Pregnant and Teen Mom followed their journey.
Recently, Catelynn - who is now four months pregnant - admitted: "We couldn't give Carly the future she deserved and so we chose adoption. We stand behind our decision. But I'm not 16 any more. We're ready for a baby."
