They're baaaack.
During Monday night's episode of Teen Mom OG, MTV revealed that Teen Mom 2 will be returning for a ninth season on January 14.
And based on the first trailer, it looks as though we're in for a doozy.
The birth of Chelsea Houska's third child, Leah Messer's relationship with Jason Jordan, and Jenelle Evans' 911 call after being assaulted by her husband will all be featured.
Needless to say, almost a decade into its run, TM2 is far from running out of steam.
Take a look:
1. The Past Is Back

That's the trailer for Teen Mom 2 Season 9. But based on the first trailer, it seems the Moms are all looking to the future.
2. Drama, Drama, Drama

Here's the first official preview of the show's ninth season. And it looks as though change is afoot for the entire cast.
3. Guess Who's Back?

Interestingly, the trailer does begin with some blast from the past moments, as Jenelle reconnects with her first baby daddy.
4. Kail's Mom

Kailyn Lowry's estranged mother will apparently also factor into this season. Based on the trailer, we're guessing that reunion doesn't go well.
5. A Tense Relationship

Kail has blasted her mom in the past for her negligence and destructive alcoholism.
6. Flashback to the Bad Times

Kail's not the only one dealing with the fallout from a relationship she'd rather forget, as Chelsea Houska is forced to once again lock horns with Adam Lind.
