The latest Teen Mom OG trailer contains a number of shocking moments.
We have Amber Portwood excitedly talking about marrying Matt Baier. (Thankfully, the two have since called the wedding off.)
We have Farrah Abraham telling her boyfriend (with a straight face ) that she's "never crazy."
We have Taylor McKinney's surprise proposal to Maci Bookout.
But that's mostly stuff we've seen before.
In fact, you can check out extended footage of all those moments in the slideshow below:
The moment that really has fans buzzing today involves the increasingly strained relationship between Catelynn Lowell and Tyler Baltierra.
An earlier clip from the forthcoming season showed Baltierra fat-shaming Lowell and criticizing the size of the meal she was eating at the time.
Now, it looks as though the problems between Lowell and Baltierra may go even deeper than previously thought.
Back in March, Lowell checked into rehab to be treated for depression and anxiety issues.
In the clip above, we see for the first time the severity of Catelynn's emotional anguish in the days before she decided to seek help.
We also see Tyler makes worse in shocking fashion.
Perhaps we was trying to help.
Maybe he just wanted to speak to his spouse as forthrightly as possible.
Whatever the case, many fans were shocked to hear Tyler tell Catelynn that she's "not ready to be a mother" in the clip above.
As fans of the series know, Tyler and Catelynn put their first child up for adoption.
So the comment is a particularly low-blow coming from Tyler.
Hopefully, the full scene will show him immediately apologizing.
