For real tho 😂#someday #notyet

A post shared by Catelynn Baltierra (@catelynnmtv) on

"For real though. #someday #notyet," she captioned the meme.

The MTV star fueled rumors she was pregnant back in November after sharing this photo — featuring her fellow married costars, Maci Bookout and Taylor McKinney. She also revealed on an episode of Teen Mom OG that she does want to expand her family. This wasn't the first time this was discussed — as Catelynn and Tyler had a similar conversation in December 2015.

“If the next one is a boy, I’m done,” adding, “If it’s not, then we’ll probably try for a third but I’m done after that.”

Catelynn and Tyler gave their oldest daughter, Carly, up for adoption.

We would love for them to welcome a new addition!
