If you've been watching this season of Teen Mom 2, you know that Chelsea Houska was not thrilled that her daughter, Aubree, had a half-sister on the way. After her ex, Adam Lind, got his girlfriend Taylor pregnant, Chelsea discussed how upset she was about the whole thing. In fact, when Taylor was seven months pregnant, Chelsea and Adam still hadn't told little Aubree about the baby.
In this sneak peek from tonight's episode, however, the baby is here and there's no hiding it anymore. So, what happens when Aubree meets her half-sister? Well, for starters, Aubree is exactly as cute as we expected her to be. "I'm your big sister," Aubs says when she meets her. But then things got a little awkward for a second when Aubree reminded us that despite her maturity, she's still only 4 years old. "I'm gonna show her to my mom later," she proudly declared.
Um...yeah, about that. To see how Adam responded, check out the video above.
