Teen Mom 2 is back and bringing more drama than ever! We’ve kept up with the fab four over hiatus, and believe us: Tissues are a must during this emotional season. You might shed a few tears just from watching the preview!

Check out what to expect from Leah, Kailyn, Chelsea and Jenelle when Teen Mom 2 returns on December 6!

Things definitely aren’t looking up in Leah’s world. Not only is she dealing with her daughter’s health problems, her marriage with Corey is on the rocks.

These two filed for divorce months ago, and now we’ll finally get a first-hand account of just what went wrong. Could the rumors be true? Did Leah cheat on her man?

Sigh, maybe those camo-tuxedos weren’t the wedding good luck charm we thought they’d be ....

KAILYN

It’s drama-rama as usual in Kailyn’s world. From the looks of things, she’s still on bad terms with her baby daddy, Jo, and they aren’t about to make up anytime soon. Or are they?

On top of everything else, Kailyn totals her car this season and might have to move in with Jo. Will this sudden change cause her boyfriend to break up with her? Love triangle alert!

CHELSEA

As usual, Chelsea is madly in love with her baby daddy, Adam, and as usual, he wants nothing to do with her. How many times does this boy have to prove what a jerk he is for her to get the picture?

Let’s just hope Chelsea manages to get over Adam and learn how to be a strong, independent woman. (Yes, we’ve been listening to a lot of Kelly Clarkson lately ...)

JENELLE

Oh, Jenelle. In case you’ve been living under a Teen Mom rock, this girl has had a rough year full of cat fights, jail time and the scent of Kieffer’s patchouli cologne, and now we finally get to see what went wrong!

From the looks of the preview, Jenelle got into a parking lot brawl, was kicked out of her mom’s house (again) and went on “an airplane.” Yeah, we all know what that means. See you in the clink, girlfriend!
