Recently the cast of Teen Mom 2 opened up about life in front of the cameras and how being able to look back has informed their decisions moving forward.

Jenelle Evans Claims Her Education Isn't A 'Joke'  

"We just all kind of forget what we do film…" revealed Jenelle Evans during the reunion episode, which aired on MTV Wednesday (featured below). "And then we watch and we're like 'woah' yeah we went through some stuff."

Having seen good times and bad during the past five seasons, there are at least a few things the moms regret and would change if they could go back and do things differently.

For Evans, it wasn't so much her decision as it was something boyfriend Nathan Griffith did. "I think that the whole Nathan's arrest thing…" she explained, "The hate he's received and anytime he just talks to anyone online or anything it's just always about… 'Oh DUI, DUI, DUI."

Laura Messer and Chelsea Houska were more concerned about decisions that emotionally strained them or their children. When it was Kailyn Lowry's turn t spill all, however, she surprised everyone in regretting something that had seemed like a happy occasion when it aired during season five.

"I wish my Mom never came to my house…I just don't want her in my life," admitted Lowry, holding back the tears. She came in and she let us down real quick and now I regret having her come in for that brief time."

Now that production has ended for season five, the stars can get back to everyday life with the raising of their children, school, and even charity events aided by their involvement and celebrity status.

The Teen Mom 2 Reunion Special aired on MTV Wednesday, October 8 at 10 p.m. E/PT.
