When viewers last saw Jenelle, Kailyn, Leah and Chelsea, the foursome were facing some brand-new beginnings -- and when "Teen Mom 2" returns for a seventh season on March 21, the young mothers will endure exciting moments as well as face difficult obstacles like never before.
In the first official look at the upcoming installment, below, the cast members can be seen experiencing life-changing milestones, readying themselves for co-parenting battles and enjoying lighthearted occasions with their MTV munchkins (Isaac is a boy boy now all right!).
For starters, Jenelle is working to balance a new relationship with David while trying to regain custody of firstborn Jace from her mom Barbara. In addition, the mother of two is facing serious legal issues with her ex Nathan and his new girlfriend. But that's only the beginning: David and Barbara can be seen clashing, with the grandmother declaring her daughter's new love interest is the "worst boyfriend she's ever had."
Meanwhile, after a contentious court battle, Leah loses full custody of the twins to Corey -- and as a result, everything is upended for the parent of three. "What's life without your kids?" Leah painfully asks.
In addition, Chelsea and Cole are going strong -- and even engaged! -- but her former partner Adam threatens to take the mother of his child back to court. Will this ruin Chelsea's happily-ever-after?
Lastly, Kailyn must adjust to life without her husband Javi: The airman is deploying and forced to say goodbye to his family for a lengthy period of time. Kail is also working to repair relations with her ex Jo -- but can the erstwhile couple get back to cordial terms while raising their son?
