VIDEO: Tyler Baltierra's Sister Says Butch Tested Positive for Cocaine in New 'Teen Mom' Sneak Peek

We've followed members of the Teen Mom OG family since the series premiered in 2009--all the ups, downs, and scary situations included. One of the most difficult parts of Tyler Baltierra and wife Catelynn Lowell's lives has been dealing with their parents, particularly their drug addiction.

As we previously reported, Tyler provided an update on Butch's drug addiction while on Kailyn Lowry and Lindsie Chrisley's podcast Coffee Convos in June, revealing his dad had relapsed after over a year of sobriety. Now, in a sneak peek for next week's episode of Teen Mom OG, we see the reality star deal with not knowing what's going on with Butch--and then his sister dropping a bombshell.

As reported by OK! Magazine, the clip shows Catelynn asking her husband, "Do you even know how your dad is doing?" Tyler replies, "Not really, no." The sneak peek then cuts to Tyler's sister Amber announcing, "Last week he tested positive for cocaine."

Back in January of this year, Tyler took to Instagram to share how happy he was for Butch and Amber for their journey to sobriety. "After seeing these two at their lowest & now seeing them sober & steadily climbing, I just can’t say enough how proud I am of both of them!," he wrote in a heartfelt caption.

Since, it looks like Amber has remained sober (as far as we know from the current season of Teen Mom OG), but unfortunately the same cannot be said for Butch. We're keeping Tyler in our thoughts as he continues to deal with this awful situation.
