'Teen Mom 2' Leah Messer Feud with Jenelle Evans, Chelsea Houska, Kailyn Lowry: 'Doesn't Talk' to Costars!

Teen Mom 2 star Leah Messer is going through hell with her impending divorce from Jeremy Calvert. However, the MTV star now has even more problems on her hands with a feud with her reality costars Jenelle Evans, Kailyn Lowry, and Chelsea Houska.

"Jenelle hasn't talked to Leah or Jeremy about the divorce or Leah going to rehab," a source told Radar Online. "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."

Not only has the mother of three not confided in her castmates about the drama in her life, but apparently has cut them off entirely.

"Leah doesn't talk to any of the other Teen Moms," another source told the gossip site. "Her costars aren't her main support system and never have been."

As MStars News reported, the reality mom has been going through bouts of depression dealing with the separation from husband and a possible rehab visit for drug dependency.

According to an In Touch Weekly report, she is "extremely depressed" and "her family is begging her to hold it together until [rehab]."

The gossip mag went on to say at her sister Victoria Messer's recent wedding "she seemed completely miserable" and "bemoaned having to pose for a group photo after the ceremony and asked her friend to drive her and her kids to the reception — but two-year-old Adalynn wasn't even in a car seat."

"She's telling everyone that she's going away for therapy," the source continued.

Nonetheless, her mom Dawn Spears took to her daughter's Facebook to deny that Leah is going to rehab or that she has a drug addiction.

"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."

Do you think Leah should lean on her costars for advice and help?
