Matt's Bombshell Confession! Amber Portwood's Fiancé Baier Admits To Lying About Drug Use: 'I Relapsed A Few Times!'

Matt Baier is finally coming clean.

In a shocking sneak peek clip for Teen Mom OG, Amber Portwood's future husband opened up about the day he made the decision to be sober. "I did absolutely exaggerate the length of my sobriety, even with her when I met her," he explained. "I had tried to get sober, I relapsed a few times."

Amber added, "When we got together, he was not sober, when I met him and I knew it." She explained how she didn't take the situation lightly and revealed, "I can say he would not be sober if it was not for me because I took those f*****g pills and poured them down the toilet and threw it at him."

And Matt definitely is aware of the impact the reality star has made on him. "But that was the day my sobriety really, really kicked in. It was either her or drugs, and I wasn't giving up her," he confessed.
