Jenelle Evans and her boyfriend, David Eason, will soon be the proud parents of a baby girl. After announcing her baby news in August of this year, just days before she and Eason hit the red carpet at the MTV Video Music Awards, the "Teen Mom 2" star continued to update fans on her pregnancy, and, in the latest update, she has revealed that she and Eason have less than a month to go before they meet their child.

“It’s officially the 30 day countdown until our little girl arrives,” Evans tweeted to her fans and followers on Wednesday, December 28, adding the hash tag, “#BabyFever.”

Jenelle Evans' baby will be her third

When fans first met Evans on MTV's "16 & Pregnant" in February 2010, she was pregnant with her first child, son Jace.

Then, in June 2014, she welcomed her second child, son Kaiser. Meanwhile, Eason also has two older children, daughter Maryssa, who has been seen on the show, and son Kaden.

Jenelle Evans and David Eason have been dating since 2015

Evans and Eason struck up a romance at the end of last year, months after Evans' engagement to Nathan Griffith, Kaiser's father, was called off, and, a short time later, they moved in together. Since hitting it off, Evans and her boyfriend have shared their romance with fans on "Teen Mom 2" and from the looks of things, their courtship is far healthier than Evans' past relationships, which have been plagued by fighting and arrests.

While Evans and Eason appear to be quite serious and stable within their relationship, they do not appear to have any immediate plans to wed. Instead, they seem to be focused on their growing family and their new home in North Carolina. Earlier this year, around the time she announced her pregnancy, Evans revealed she and Eason had purchased land and intended to build their dream home on their property.

To see more of Jenelle Evans and her growing family, as well as her co-stars, Chelsea Houska, Leah Messer and Kailyn Lowry, tune in to "Teen Mom 2" season 7B, which premieres on MTV on Monday, January 2, at 9 p.m.
