Fights, Friends & Foes! Find Out Who’s Secretly BFFs & Who Hates Each Other In The 'Teen Mom 2' Cast REVEALED

They've known each other since they were all sixteen and pregnant, but the ranks of the Teen Mom 2 cast are crumbling! Several sources close to the cast tell RadarOnline.com that the dynamics among the girls have changed -- and not always for the better!

Once upon a time, the girls of Teen Mom 2 — Jenelle Evans, Kailyn Lowry, Chelsea Houska, and Leah Messer — all smiled as they promoted their hit MTV show together.

Now, insiders say Messer is distancing herself from the group. "Leah doesn’t talk to any of the other Teen Moms," a source tells Radar.

Houska is also living outside the group, according to sources. "Chelsea also doesn’t talk to her costars," another insider claims. "She keeps to herself."

But at least Lowry and Evans are still close. "It seems like Jenelle and Kailyn are the only ones close now," the insider says. "Kailyn is friendly with everyone," another source confirms. "She’s friends with all of them, but just doesn’t talk to everyone all the time."​
