"Teen Mom 2" co-stars Jenelle Evans and Leah Messer are feuding after Leah made a comment that Jenelle didn't like involving the recent reunion drama from the season finale of the show. During the episode, Jenelle was very upset about a confrontation she had with her mother, Barbara, about custody of her oldest son, Jace. Jenelle was also pregnant at the time and claimed not to be feeling well. After filming her individual segment with her mother, Jenelle told producers that she wanted to leave the show and go home because she felt ill. Later, when Leah Messer found out about Jenelle leaving, she said that she didn't care about it, but that Jenelle should be there because it was her job.

To make matters worse, Jenelle's "Teen Mom 2" co-star, Chelsea Houska, who was also very pregnant at the time, left the show early as well. Chelsea said she was also not feeling well and had a fever. The MTV crew was very supportive of Chelsea's decision to leave and didn't question it at all. When Evans found out how all the drama played out, she responded to Leah Messer about her comments. Jenelle tweeted to Leah, "Tell me how you feel! I was sick and pregnant with heartburn. You know nothing so don't comment."

Evans also slams Chelsa's father, Randy Houska, after he tweeted about the reunion.

Jenelle Evans didn't stop her Twitter assault at Jenelle Evans.

She also called out Chelsea Houska's father, Randy Houska, who tweeted that he was "bummed" about missing the last two reunions because they can be "fun, " and there are provided "catered food and snacks." Jenelle seemed to think Randy's tweet was a dig at her and replied, "Keep being immature Randy, says a lot about your character." The "Teen Mom 2" grandfather has since deleted the reunion themed tweet.

So far, Leah Messer, Chelsea Houska, or Randy Houska haven't responded to Jenelle's tweets calling them out about the reunion. It should be interesting to see if the "Teen Mom 2" stars have anything to say to each other in the coming days.
