Seriously — can she get any cuter?! Like most of the Teen Mom OG fans, we are OBSESSED with Catelynn Lowell and Tyler Baltierra's daughter, Novalee — who will turn three years old on New Year's Day. It feels like just yesterday the MTV fandom welcomed the little blonde bombshell into the fold, so she certainly is growing up fast. Catelynn and Ty tied the knot in August 2015 and are also the biological parents of a daughter named Carly — whom they placed up for adoption as teenagers.

The famous mama recently made clear just how much little Nova means to her in a heartfelt Instagram post after a tragic shooting took place near their home. "My world, my baby," she wrote. "I'm going to be holding you a lot closer and a lot tighter — and I'm never letting you go." We definitely felt the love in those words!

There's a chance Nova will become a big sister one day, as the Conquering Chaos authors have discussed having another baby. Scroll through the gallery to see all of Nova's cutest moments from 2017!
