'No Drugs, No Drinking!' Amber Portwood & Matt Baier Reveal STRICT Rules To Chris Baier In A 'Teen Mom OG' Clip

Amber Portwood and Matt Baier are laying down the rules!

In a sneak peek clip for Teen Mom OG, the couple welcome Matt's son, Chris Baier, into their home and offer him a place to stay. The two are hoping they will be able to change his ways after his past of drug and alcohol abuse.

"So you don't have to worry about sitting around the house, you are an adult, you can do what you want, just remember no drugs, no drinking in the house and stuff like that because we can't be around that either," Matt told his son. "This isn't a revolving door, we are not here for a vacation, we are here to help you, but we are not going to enable you in any way, make sense?"

Matt asked his son if he would be willing to attend a program and meetings, which Chris was quick to shut down. "I just want to leave it in my past, I don't want to go and talk to people," Chris explained.

Watch Amber and Matt welcome Chris into their home in the clip above! Teen Mom OG airs Monday nights at 9PM ET on MTV!
