'Teen Mom 2' Fight: Leah Messer, Chelsea Houska, Kailyn Lowry, Jenelle Evans Not Friends!

Teen Mom 2 stars Leah Messer, Jenelle Evans, Kailyn Lowry, and Chelsea Houska seem very friendly when they get together for reunion specials, but outside of the hit MTV reality series, some of the drama-filled foursome can't stand each other.

According to Radar Online, Leah, who is going through a nasty divorce from husband Jeremy Calvert, doesn't have anything to do with her castmates. However, the West Virginia native isn't the only one.

 "Chelsea also doesn't talk to her costars," a source told the gossip site. "She keeps to herself."

The same can't be said for the other two reality moms.

"It seems like Jenelle and Kailyn are the only ones close now," the source said. While another source claims, "Kailyn is friendly with everyone. She's friends with all of them, but just doesn't talk to everyone all the time."

As MStars News reported, Leah is probably going through the toughest time out of all the girls, but leans on family and friends rather than any of her fellow MTV Teen Moms.

"Jenelle hasn't talked to Leah or Jeremy about the divorce or Leah going to rehab," a source told Radar. "Jenelle has no idea why Leah hasn't talked to her about the situation. But Leah won't talk to any of her costars about it either."

"[Leah's] costars aren't her main support system and never have been," the source continued.

This comes on the heels of Leah's mother Dawn Spears denying on Facebook that the MTV star is going to rehab or that she is addicted to drugs.

"TRUE FANS listen up. Leah is NOT going to rehab lol. This is Momma Dawn and I 100% ASSURE you that Leah is NOT going to a DRUG REHAB," she wrote. "Lots of LOVE to the true fans. all will come out on the upcoming show about Leah Dawn Calvert, Jeremy, [Leah's ex-husband] Corey, [Corey's wife] Miranda, and the babies. But rest assure I HATE drugs don't want association with them and wouldn't NEVER Condone them."

Are you surprised that the Teen Mom 2 girls aren't that close?
