Leah Messer's life is falling apart around her as she goes through a divorce from her husband Jeremy Calvert and a reported stay in rehab for a pill addiction.
But despite the tough times, RadarOnline.com is exclusively reporting that Messer is not turning to her Teen Mom 2 costars for help.
"Jenelle Evans hasn't talked to Leah or husband Jeremy Calvert about the divorce or Leah going to rehab," a source tells Radar.
Evans isn't the only one outside of Messer's inner circle.
"Jenelle has no idea why Leah hasn't talked to her about the situation," the source says. "But Leah won't talk to any of her costars about it either."
"Leah doesn't talk to any of the other Teen Moms," a second insider confirms.
Instead, Messer has been leaning on other people to support her through this rough time.
"Her costars aren't her main support system and never have been," the insider explains.
As Radar previously reported, the mother of 5-year-old twins Aliannah and Aleeah and 2-year-old Adalynn allegedly left her native West Virginia for an undisclosed treatment facility on May 3.
According to reports, Messer will be gone about a month — but hopes that her daughters will be able to visit her.
There is one person who probably won't be visiting her though: her soon-to-be ex-husband.
While in rehab, Messer will be able to discuss her split from her husband and how he cheated on her with tattoo model Melissa Marie.
