"Time to introduce the world to our baby girl soon, Ensley Jolie Eason," Jenelle captioned the loving photograph and gender announcement above. "She will be arriving Jan. 28th. We couldn't be any happier!" Break out the pink balloons!
David also shared a snapshot of the sweethearts kissing and declared he "can't wait" to meet their daughter.
As fans of the long-running series know, Jenelle is mom to six-year-old son Jace -- whom she memorably welcomed during 16 and Pregnant back in 2010 -- and two-year-old son Kaiser (who was born during the fifth installment of the reality program). David, who is also a parent, made his TM2 debut last season and viewers got to watch their romance flourish in front of the camera -- from an important relationship step (Jenelle introducing David to her mom Barbara) to David becoming a support system during Jenelle's legal and health issues. And now, they're gearing up for life as parents of their very own munchkin!
