'Teen Mom 2' Leah Messer Custody Battle Brewing: Exes Jeremy Calvert & Corey Simms Now Friends!

Teen Mom 2 star Leah Messer has just gotten out of rehab, but her problems aren't over. Apparently, the MTV star's ex-husbands Jeremy Calvert and Corey Simms have taken a united front when it comes to dealing with Leah and custody of their kids.

"Though they used to fight, Corey and Jeremy have a great relationship now," a source told Radar Online. "They obviously dealt with a lot of the same issues. And now that they talk, Jeremy can see Corey's side in his past arguments with Leah."

While the reality mom was in rehab, Jeremy and Corey made sure that their daughters Ali, Aleeah, and Adalynn constantly saw each other to keep their sibling bond.

"They arrange visits because they don't want the sisters to be separated all the time," the source said. "It's important to them that they all have a close relationship."

As MStars News reported, there's a bitter custody battle brewing between Leah and Corey that almost derailed her attempt to go to rehab.

"With her drug and emotional issues, Corey doesn't think Leah is in any shape to be a good mother right now," another source told Radar. "He will stop at nothing to make sure his girls are in safe hands."

"When Messer caught wind of Simms' plan to take the twins away, she initially refused to go to rehab until the problem was sorted out," according to Radar. "But Simms hesitantly agreed to hold off on legal proceedings until she finishes treatment."

Even though Leah and Corey look like they are in store for a long custody war, it seems that the situation is settled between the mother of three and her second husband.

"When Leah comes home, they will share joint custody of Addie," the source told the gossip site. "Jeremy doesn't want to take his daughter away from her mom."

Do you think Jeremy and Corey becoming friends is bad news for Leah?
