'Teen Mom 2' Leah Messer Custody Taken Away In Rehab: MTV Star's Girls Separated From Each Other!

Teen Mom 2 star Leah Messer is still in rehab dealing with her personal issues with her three girls being separated from their mother for weeks. Now, it seems as though the MTV star's family has been pitching in to help take care of the kids while she is away.

According to In Touch Weekly, during the divorce proceedings Leah and ex-husband Jeremy Calvert hammered out a custody agreement for their adorable 2 year-old.

"The terms, including a custody arrangement for Adalynn, were agreed upon prior to the hearing. It was all over in about 15 minutes," a source said.

Radar Online is reporting that while the reality star is in rehab, Jeremy's parents, Tammy and Anthony, have custody of little Addy.

The MTV dad is away for work in Ohio doing pipeline engineering.

The twins, Ali and Aleeah, are currently with their father Corey Simms and his wife Miranda. Luckily, all involved make sure all three girls see each other while their mother is away in a Utah rehab facility.

"Jeremy wants his daughter to have a relationship with her older sisters," a source told Radar. "He wants to make sure she doesn't have to deal with too much change in her life."

As MStars News reported, it wasn't pill popping that drove the mother of three to rehab.

"A source close to Leah noted that the reality star is in for depression and stress, not drug use," US Weekly reported. "She was originally signed up for a 30-day stint, but could be released early. It currently looks like she will check out of rehab at the end of June."

"Leah didn't exactly go willingly, however. The production source tells The Ashley that the show's producers had to essentially force Leah to go," according to The Ashley Reality Roundup. "They used something in her contract terms to force her to go to rehab... producers basically refused to continue their contract with her until she went."
