Jenelle Evans and the cast of Teen Mom 2 are filming the upcoming season of the MTV reality series.

Just over a month after Evans and her boyfriend, David Eason, revealed they were expecting their first child together, a baby girl, the reality star continues to film her pregnancy journey.

"I think I might just film in this shirt ... so comfy lol," Evans wrote in the caption of one of her latest Snapchat posts, according to a report by In Touch Weekly on Thursday.

In August, days before walking the red carpet at the MTV Video Music Awards, Evans and Eason took to Instagram, where they shared the first photo of Evans' baby bump and revealed they were expecting a baby in January.

"Time to introduce the world to our baby girl soon, Ensley Jolie Eason. She will be arriving Jan. 28th. We couldn't be any happier!" Evans wrote with the photo below.

"IT'S A GIRL YALL!! I'm so happy im bout ta cry!! I love you so much @j_evans1219 and I cant wait to meet our baby girl Ensley Jolie Eason!!" Eason added along with a photo of Evans' bump.

Evans and Eason began dating at the end of last year after Evans' messy split from Nathan Griffith, the father of her second child, Kaiser.

Evans is also mom to 7-year-old Jace from her past relationship with Andrew Lewis.
