Chelsea Houska DeBoer is keeping it real when it comes to being a ‘Teen Mom.’ The proud mother of three opens up about being a ‘Teen Mom’ at 29 years old, and reveals how she’ll know when to walk away from the show after over a decade of sharing her life. Chelsea also shows off her new baby bump and talks about the excitement of welcoming baby no. 4. She also weighs in on whether she and husband Cole would ever consider doing a spinoff series about their family and life together, plus, the journey of building their dream home. We also take a walk down memory lane as Chelsea hilariously reacts to seeing old photos and footage of herself. ‘Teen Mom 2’ premieres Sept. 1 on MTV.
