"Teen Mom OG" stars Catelynn Lowell and Tyler Baltierra will celebrate their daughter Nova's third birthday this winter, but they may be ready to expand their family already. The MTV spouses are reportedly ready to have another child, and fans are excited for the fan-favorite couple to grow their adorable little family. As many "TMOG" fans know, Tyler and Catelynn share two children together, Carly, whom they placed for adoption when they were teenagers, and little Nova.

Big baby news coming soon?

According to Radar Online, "Teen Mom OG" fans recently asked Catelynn Lowell's husband, Tyler Baltierra, when viewers can expect another pregnancy announcement from them, and Tyler stunned some fans when he replied, "Hopefully soon." Does this mean that Catelynn is already pregnant with the couple's third child?

It's possible. Many women choose not to announce their pregnancies until they are out of their first trimester, especially people in the public eye. However, the couple wouldn't be able to hide any pregnancy news for long since they have MTV cameras filming them constantly.

Ready to expand their family?

It's likely that Catelynn Lowell and Tyler Baltierra are not currently pregnant, but that they are discussing having another baby in the near future, or even trying to get pregnant currently. The "Teen Mom OG" stars have made no secret about wanting to have a bigger family. They've even mentioned adopting a child to give it a good home, much like adoptive parents, Brandon and Theresa did for their daughter, Carly.

However, Lowell's struggle with anxiety and postpartum depression has caused some issues when it comes to making the decision to expand their family.

Another 'TMOG' baby?

In the newly released trailer for the upcoming season of "Teen Mom OG," Catelynn Lowell is seen playing with her daughter Nova as she reveals that she can't let her fears dictate the things she wants out of life, and if one of those things is having another baby, it seems that viewers could see Cate and Tyler make the big decision to give Nova a younger siblings in an upcoming episode.

Meanwhile, the couple's co-star, Amber Portwood, is currently expecting her second child with boyfriend Andrew Glennon. Amber is already the mother to daughter Leah, whom she shares with former fiance Gary Shirley, and the child will be the first for Glennon, who Portwood met while filming "Marriage Boot Camp" with her ex-boyfriend Matt Baier.
