MTV's Teen Mom 2 starring Jenelle Chelsea Leah and Kailyn

MTV unveils it’s newest additions to the Teen Mom franchise when Teen Mom 2 premieres January 11, documenting the further adventures of 16 and Pregnant vets Jenelle Evans, Leah Messer, Chelsea Houska and Kailyn Lowry.

In case you needed a refresher on the girls, MTV has released an emotional trailer for Teen Mom 2 that will remind you about each of the girls’ backstories by offering a sneak peek at clips from the upcoming show:

Here’s the cast with a brief synopsis of some of the things we have to look forward to this season:

Leah Messer from Teen Mom 2 on MTV

Leah Messer and Corey Simms reconcile while struggling through medical issues with one of their twin daughters, Aliannah and Aleeah. The reconciliation culminates in an emotional wedding ceremony – the first for the Teen Mom franchise!

Kailyn Lowry from Teen Mom 2 on MTV

Kailyn Lowry and baby daddy Jonathan “Jo” Rivera’s relationship is strained as Kailyn struggles with two part-time jobs and attending college. Things go from bad to worse when Kailyn starts dating other people while still living in the basement of Jo’s parents’ house. “I met someone at work,” she says in the trailer. “But he’s really dumb though.”

Jenelle Evans from Teen Mom 2 on MTV

Foul-mouthed firecracker and preggo pot puffer Jenelle Evans continues her partying ways and as a result faces a custody battle for her son Jace with her mom Barbara. (She appears to assault her mom Amber Portwood style, so I’m sure Jenelle is destined to make a lot of headlines this season!)

Chelsea Houska from Teen Mom 2 on MTV

Chelsea Houska is still seeing Adam Lind, the father of her daughter Aubree, but the relationship is still rocky. Chelsea moves in with a friend and contemplates attending beauty school as her friends and family pressure her to end things with Adam.
