Teen Mom 3 might be off the air (noooooo!), but this short-lived reality show's fleet of stars are just as fascinating as ever. The MTV reality show featured a great group of kids, all of whom struggled with their daunting role as teen parents. But guys? No one has embraced fatherhood more dramatically than Alexandria Sekella's baby daddy, Matt McCann!

Matt's road to daddyhood hasn't been easy, and fans will remember that he pretty much rejected both Alex and their daughter, Arabella, on 16 and Pregnant. Matt's behavior went from bad to worse on TM3, but a lot of this hunk's inability to parent can be attributed to his struggle with drug addiction.

Matt was hooked on heroin for much of his run on the show, but we're thrilled to report that he's been clean and sober for just shy of two years.

"22 months clean [off] heroin," Matt tweeted on March 2.

Amazing! Beating addiction is a notoriously hard process — just ask Teen Mom 2's Jenelle Evans — and it's amazing that Matt has been sober for close to two years. In the past 22 months, Matt has not only regained control of his life, he's gotten engaged, and he's majorly manned up in the daddy department. Matt currently has regular visitation with Bellie, treats her like the princess she is, and even seems to be working slightly harder on co-parenting with Alex!

Are you proud of Matt's commitment to sobriety? Hit the comments!
