Amber Portwood and her fiance, Matthew Baier, are currently living with his son, but despite prior reports, Chris did not move in with the Teen Mom OG couple after ditching his pregnant girlfriend.

In a new interview, Chris' girlfriend is speaking out. 

“When Christopher left, he left to go get help with his drug addiction. We had no idea I was pregnant until he was already gone for four or five days,” Madonna confirmed to Real Mr. Housewife on Friday. “Christopher was the first person I told when I found out I was pregnant. He was excited but at the same time he’s in Indiana with Matt and Amber trying to get help with his addiction. He’s better off where he’s at right now then trying to come back here and still struggle with addiction and possibly relapse again.”

“Christopher did leave but he did not have any idea that I was pregnant. I did not have any idea at that point, either,” she continued. “I want Christopher to get better for himself, and for our child. Both of us are working on ourselves right now. I hope that he can get sober totally and be in our child’s life.”

According to Madonna, she's completely supportive of Chris' move and hope they can eventually be great parents together.

“He went to get help with his drug addiction,” she explained. “He has a job now and he is doing good where he’s at. When we have our kid, we will figure out what to do. I don’t want him to come back here and relapse.”
