She captioned the snap, "#it'sofficial #4months <3" which we're pretty sure everyone and their mother can figure out, but just in case: she's four months pregnant. Pound sign. Heart.

Catelynn gave her first child (Carly, now 5) up for adoption on Teen Mom after giving birth during MTV's 2009 series 16 and Pregnant.

She and Baltierra were previously engaged but eventually decided to call things off on VH1's Couple’s Therapy. Like you do.
