Jeremy Calvert is glad to see his ex-wife, Leah Messer, in a healthy place following a number of years of public struggles on "Teen Mom 2." During an interview with The Ashley's Reality Roundup on May 14, Calvert addressed his ex's 2015 stint in an Arizona rehab facility, claiming Messer is now "doing great for herself.”

“I’m really proud of [Leah] for straightening up and getting back on her own two feet," Calvert said of his former wife. "That’s [Adalynn]’s mother, I want her to be happy.” Calvert and Messer got married in 2012 and remained married until 2015 when Messer began to face struggles that were chronicled on "Teen Mom 2." As fans will recall, Calvert and Corey Simms, Messer's first husband, accused Messer of having a problem with prescription pills, but she denied it.

After being seen slurring her words during a phone call with her daughter Ali's doctor and nearly nodding out while holding the infant son of her sibling, Leah Messer entered rehab but claimed she was doing so only to treat issues with anxiety and depression -- not drug addiction. That said, rumors continued to swirl due to her odd behavior on the show.

Leah Messer is twice divorced

When fans first met Leah Messer on "16 & Pregnant" season two years ago, she was involved in a romance with Corey Simms, the father of her twin girls, eight-year-old Ali and Aleeah, who she married in December 2010. However, their marriage didn't last and just about six months after they tied the knot, Messer filed for divorce after admitting to cheating on Simms days before their wedding with her former boyfriend Robbie Kidd.

Just a few months after her split from Simms, Messer began dating Calvert and about six months later, the couple got married. One year after that, they welcomed their daughter Adalynn, now four.

In late 2014, Leah Messer began facing allegations of cheating on Calvert with Kidd and although she denied those reports, Calvert didn't seem to believe her and ultimately filed for divorce.

Months later, he moved on with his now-ex-fiancee Brooke Wehr as Messer began dating Theodore "T.R." Dues.

Leah Messer is single

At the moment, Messer seems to be staying single as she focuses on her daughter and her career on MTV.
