Custody Battle Heats Up On 'Teen Mom 2'

Evans has struggled with drugs and abusive relationships, which ultimately led to her mother, Barbara, stepping in taking custody of her newborn son Jace, now five. These days, however, it seems that Evans has turned over a new leaf. She's back in school and raising her newborn son Kaiser with live-in boyfriend Nathan Griffith.

The reality star still hasn't gotten custody back of Jace, but based on this week's episode of Teen Mom 2 it looks like she's working on it, even if the situation is complicated. After the episode aired on Wednesday Evans voiced concern about a potential custody battle, especially since she and her mom have only just started to get along.

If Evans really does have her family's best interest at heart, then there are bound to be some tough decisions ahead on both ends.

Teen Mom 2 continues on MTV with its fifth season Wednesdays at 10 p.m. ET/PT.
