Leah Messer's husband, Jeremy Calvert, has said that the "Teen Mom 2" star has cheated on him.

Calvert said he is filing for divorce, and fans have made their allegiance known. They are backing Calvert because of Messer's past. She cheated on her first husband, and she has supposedly cheated on Calvert with the same man that she cheated on her first time.

"Wait Leah cheated on her husband? Again?" one Twitter user said.

Another user thought it wasn't surprising that Calvert was saying that Messer cheated.

"I don't see why anyone would be surprised if Leah cheated. It's not like she hasn't cheated before. ... It's not too far-fetched imo," she said.

Calvert wrote a series of tweets where he expressed his frustration.

He explained that he was done protecting her and that he caught her. He also called out the man that she cheated on him with, Robbie Kidd.

He later deleted the tweets, but his anger was clearly noticeable in the messages. He even called Messer names.

On top of the ending of her marriage, Messer is embroiled in a legal battle with her ex-husband, Corey Simms. The two are fighting for custody of their 4-year-old daughters, Ali and Aleeah.

The mom was prescribed pills by her doctor because of the anxiety, but it only made Messer feel guilty.

"When I first take that medicine, I feel calm and I feel like I can do stuff," she said. "I took half of it this time instead of a full one and now I feel really messed up. Maybe it's just me thinking about it too much."

She explained that the medicine made her feel like she was dependent on drugs, and though her doctor warned her that she would not feel like herself at first, it was just felt like too much to handle.
