It's sooner than you might think!
I'm not completely sure why MTV is being so weird but apparently they decided to make Seasons 3 and 4 into Season 3 part 1 and 2. So the episode of Feb. 4th is the "mid season" finale. There will be a "mid season Runion Special" and then the season will pick back up Feb. 18th with the second half. That's 12 new episodes.
Unfortunately MTV hates me and wants to make everything confusing and hard to explain so in their press release they refer to season 3 part 2 as season 4. However they are advertising on MTV as I write this that Season 3 CONTINUES Feb. 18th......
“Season four will pick up immediately where season three left off, diving deeper into the lives of Chelsea, Jenelle, Kailyn and Leah as they continue to navigate the ups and downs of motherhood, life and love. From the tragic loss of an unborn child and a heartbreaking love triangle to ongoing custody battles and struggles to pursue an education, these young women will once again pull back the curtain to give viewers a raw look inside the difficulties and joys of young motherhood.”
