In January, the Teen Mom star and her fiance, Tyler Baltierra, will welcome their second child. As they get closer to Lowell's due date, the couple continues to share their journey through photos with their many fans on social media.

Lowell and Baltierra have been together for about a decade, and are currently planning a spring 2015 wedding. Fans have watched them on MTV since they appeared on 16 & Pregnant in 2009. After choosing adoption for their first daughter, Carly, Lowell and Baltierra went on to appear, alongside three other couples, on Teen Mom.

Also on social media, Lowell told fans she was experiencing fake labor pains."These Braxton hicks really hurt sometimes!" she wrote on Monday. "Is that normal?"

Last month, Baltierra expressed his excitement in meeting his new baby girl.

In an emotional Instagram post, which was accompanied by a selfie, he wrote, "Your looking at the face of a Daddy to be! I for real can't wait any longer for my little angel to get here, I can't wait to finally be able to be a father and show her the world #HurryUpBaby #ImGettingImpatient #3MonthsToGo."

Lowell and Baltierra will be seen in Teen Mom season 5 next year on MTV.
