Catelynn and Tyler are expecting their second baby together and have shared the adorable black and white picture with fans on Instagram.
In the snap, Catelynn is proudly showing off her blooming bump while Tyler is cuddling into her and gently patting his unborn child. Cute or what?
Commenting on the picture, Catelynn told her followers: "My man is the best man... he is the world's most amazing father, love him with all my heart and soul."
Catelynn and Tyler first found fame after starring in MTV's 16 & Pregnant. At the time, Catelynn was expecting their first child, a daughter called Carly, and they later made the decision to give her up for adoption.
The couple, who were just teenagers who'd had tough upbringings, felt they were unable to give Carly the life she deserved but they have kept in touch with the tot through her adoptive parents, Brandon and Teresa.
Earlier this year, Catelynn revealed that she and Tyler were trying for another baby as they finally felt financially and emotionally stable enough to bring up a child.
Now pregnant with another daughter, Catelynn has also shared a photograph of a very special gift she and Tyler have received for their unborn child.
Alongside the picture of two pink baby dresses and a material dolly, Catelynn explained: "The BEST gift for our new little girl was from Brandon and Teresa... Carly's first baby doll and two outfits she wore as a baby...
"I about balled and this is the most precious thing to me now.... for our daughter to have some of Carly's things are beyond amazing and touching... something I will never forget..."
How lovely. We just can't get enough of this adorable couple!
