The ladies from Teen Mom 2 have filmed the Season 3 reunion and are filming Season 4. It is said to also be the last season of Teen Mom 2. According to wetpaint.com the girls were excited to sign on for another season unsure if it was going to happen with the ending of Teen Mom 1.
It makes sense that Season 4 would be the last one for Teen Mom 2, and the girls are now trying to figure out how to keep money rolling in after the show is over. Jenelle is thinking of starting her own tanning salon, Kail is thinking about opening a baby boutique. Chelsea is working on her career as a hair stylist and Leah's fiance Jeremy allegedly makes more money then she does so I don't think she has much to worry about!
Good Luck Ladies!
