For over a decade, MTV’s Teen Mom franchise has documented the highs and lows of reality television’s most enduring couple, Catelynn and Tyler Baltierra. From their heartbreaking debut on 16 and Pregnant—where they made the painful decision to place their firstborn daughter, Carly, for adoption—to building a stable life together, fans have watched them grow up on screen.

However, as the Baltierras transitioned into adulthood and expanded their family, a new dynamic emerged as the heart of their story: the deep, emotionally complex relationship between Catelynn and her eldest parented daughter, Novalee “Nova” Reign.

Nova said

Catelynn Lowell and Tyler Baltierra’s oldest daughter, Novalee (Nova), expressed that meeting Carly was “one of the best things that’s ever happened”. She shared that she looks up to Carly as a big sister and wishes that Carly “would be in our family”.
