Following Jeremy Calvert's elaborate Twitter rant about his "b***h" wife being "caught" cheating on him with her ex-boyfriend, Robbie Kidd, the couple's moms went at it on Facebook.

“She know’s she’s caught and it over," Tammy Calvert wrote to her Facebook friends and followers, according to an Oct. 17 report by Starcasm. "Her own mother know what she was doing and covered for her. What’s that say about there people ... She made her choice, Now LIVE WITH IT!!!”

'Teen Mom 2' Star Leah Calvert Denies Cheating, Sister Claims Husband Didn't Want To Be Married

Earlier in the day, Dawn Spears, Leah's mom, told fans it was Jeremy's father who started the rumor. According to Dawn, Jeremy's dad told him he saw Robbie sneak in a back door on a deer cam. However, she claims to have spoken to Robbie herself, and said he told her he wasn't in town at the time.

Tammy also mentioned Leah's current custody battle with her ex-husband, Corey Simms, and threatened to report her to Child Protective Services. "Anyone know someone that works at CPS in Charleston?" she asked.

The drama between Leah and Jeremy began on Friday morning, when Jeremy took to Twitter to reveal she had cheated. Before deleting his tweets, Jeremy informed fans that he was done protecting Leah and planned to file for divorce later that day.

Although both Leah and Jeremy have remained silent since the posts were shared, Leah's sister claims to have spoken to Jeremy, who regrets his Twitter rant.

“He’s upset, you know, even though nothing happened," Victoria said during a blog radio program. "I talked to Jeremy last night and he told me, ‘I love Leah and I love the kids. I did post stuff on Twitter but I was upset.’”
