Leah Messer isn't too happy about her past divorces. As "Teen Mom 2" fans well know, Messer married her first husband Corey Simms, the father of her eight-year-old twins Ali and Aleeah, in late 2010 and parted ways with him just months later after admitting she cheated. Then, less than one year later, Messer married second husband Jeremy Calvert.

While Leah Messer and Jeremy Calvert's marriage lasted longer than her first, it didn't last long and in October 2014, Calvert confirmed plans to divorce the reality star after claiming he caught her cheating with the same man she slept with during her relationship with Corey Simms.

Later on, during a reunion special for "Teen Mom 2," it was revealed that Messer had slept with Simms during her marriage to Calvert -- and his marriage to now-wife Miranda Patterson.

Leah is twice divorced at 25-years-old

While Leah Messer has remained single for the past several months, she recently shared a text message conversation between herself and a friend in which she spoke about her embarrassment over being twice divorced.

“I feel embarrassed for being married twice,” Leah Messer wrote in a text message sent to her friend Jessica, via a January 16 Twitter post. In the caption of her post, the "Teen Mom 2" star and mother of three said that in her past relationships, there have been times when she should have said, "No."

"I wasn’t where I’m at today though," Leah Messer explained.

The reality star's latest divorce, from Jeremy Calvert, was finalized about two and a half years ago.

Leah secretly dated her trainer for several months

Two years ago, Leah Messer began facing rumors of dating her personal trailer, Theodore "T.R." Dues and a photo of the two of them spending time with Messer's daughters ultimately hit the web a short time later.

However, the "Teen Mom 2" star waited until her relationship with Dues had come to an end before confirming they were dating. Meanwhile, Corey Simms spoke about the top-secret relationship on the show, claiming that one of his daughters told him Dues was living with Messer.
