'Teen Mom 2' Star Leah Messer Calvert To Enter Rehab For Drug Abuse, Corey Simms To Seek Custody Of Twins: Report

Things aren’t easy for “Teen Mom 2” star Leah Messer. The mother of three may enter rehab for drug abuse and while she’s away, ex-husband Corey Simms reportedly wants to get custody of their twins. More, Jeremy Calvert, husband No. 2, may file for divorce, In Touch Weekly reported via Radar Online.

“She’s confessed to Jeremy that she has a problem, and knows she has no other choice than to go to rehab immediately,” a source told the magazine. In the past, Messer, 22, was accused of nodding off during an episode of “TM2” and supposedly abused prescription pills.

“I used to give Leah the pills myself; she’s picked up 30 to 40 pills at a time from me,” an anonymous source told the tabloid in October. “She was withdrawing $1,000 a week to buy pills.”

It doesn’t mean she’s going to come clean about her alleged drug use, though. “She won’t say she has a drug problem or needs rehab,” a source told In Touch Weekly. Instead, Messer will call it a "therapy intervention" so she can become a "better person.” The reality star may be gone for three to four weeks.

Now, the reality show that made her famous supports her decision and will even pay for her therapy. “The last thing they want to see is her going down the same dark path that [co-stars] Amber Portwood and Jenelle Evans did,” an insider said. “MTV would foot the bill and force Leah into rehab because the network loves her.”

While she’s getting better, Simms, who shares 5-year-old twins Ali and Aleeah with Messer, will take care of the girls and try to get primary custody, In Touch Weekly wrote. Calvert will took after his daughter, Adalynn, 2.

Simms, 25, first became interested in seeking primary custody of his daughters when he heard that Messer was abusing anxiety medicine. “We’ve heard rumors about the medication stuff and I didn’t like that. It’s Leah’s life but it’s my daughters,” he said on a reunion special for the reality series in October.

Messer has not responded to the rumors, but she did tweet two cryptic messages recently. They seemed to be aimed at her second husband.

You should never have to lie to please your loved ones and tell them what they want to hear. This is sad world these days.
