There's no denying that Teen Mom 3's Matt McCann has come a long way since his less-than-impressive days on 16 and Pregnant. This wayward gent spent his formative years as an MTV star roaming around the backwoods (no literally, he slept in the woods), rejecting his baby mama, and using drugs — but things have definitely changed for the better!

These days, Matt is in a stable relationship with his fiance, Lekota Koch, and — more importantly — he's clean and sober. Matt claims to have been drug-free for a full 18 months, which is super impressive considering that he was addicted to heroin. Relapse is quite common when recovering from addiction, and it's wonderful that Matt's been able to stay clean. However, his baby mama, Alexandria Sekella, isn't so sure that he's sober.

Matt and Alex are currently working on their co-parenting skills, and as you might expect it's not going swimmingly. Alex is hesitant to let Matt around their daughter (which is completely understandable given his past), and now she seems to be questioning his sobriety!

When a fan told Alex that Matt's been clean for 18 months, she tweeted, "He's clean from heroin not anything else."

Yikes, that's a pretty big accusation! Matt has yet to respond, but that doesn't mean you can't throw in your two cents! Do you understand where Alex is coming from?
