On the show, host Dr. Drew Pinsky suggested Simms and Messer's romance overlapped with his relationship with Miranda, leading the former couple to speak of their affair. However, off the show, Simms, Messer, and their families, continue to ignore the revelation. Instead, the families remain focused on Simms and Messer's 5-year-old twins, Ali and Aleeah.

"#ThrowbackThursday These two are the sweetest things, always have been! #aligrace," Simms' father, Jeff, captioned a new photo on Instagram on Thursday, one day after the shocking Teen Mom 2 moment aired on MTV.

Jeff also posted a photo on Instagram of a baseball field, which he captioned, "WVU baseball field. #WVU."

Although Simms has chosen to stay quiet about his affair with Messer, he isn't staying mum on his allegations against her and her rumored drug use. In fact, he insists his claims were made for good reason.

“There is a reason for everything that Miranda and myself have said or done," Simms explained to fans on Twitter. "We simply want the girls to grow up in a safe and healthy environment. There is a lot of things that has been told to us by very close members of her family that lead us to believe the things being told are very much true. If we didn’t care about the girls or the situation we would obviously not have anything to say or do about it.”
