Leah Calvert Caught Cheating On Husband Jeremy: "U Did It To Corey And Now Me!"

On Friday, Jeremy Calvert took to Twitter, where he went on an elaborate rant about the Teen Mom 2 star, claiming she had cheated on him with her ex-boyfriend, Robbie Kidd. However, according to Leah, she did nothing of the sort.

"I never cheated on my husband and he knows that... there was a rumor and he believed it but it's ok," Leah told fans on Twitter, hours after Jeremy's tweets were posted.

On Oct. 17, Jeremy called his wife a "b***h," and told fans he caught her cheating with the same man she cheated on her ex-husband, Corey Simms, with before they wed. The man, Robbie Kidd, was someone Leah dated briefly years ago.

Leah's sister, Victoria Messer, also spoke out about Jeremy's tweets, telling her Facebook fans, "You've wanted out of the marriage for awhile and now you're trying to make assumptions to make yourself look good to make people feel sorry for you. You wanna sit around and post a bunch of bullsh*t but little do you know sweetheart, we are a little smarter than you are and we actually have proof of sh*t that you've done. So maybe you should think before you start making up lies because we have hidden truth."

In July, Leah spoke to In Touch Weekly, claiming that despite their many on-camera feuds, she and Jeremy were determined to make their marriage work.

"Divorce is not an option for us,” she said. "I truly believe that Jeremy is the best thing that’s ever happened to me and my girls, and I really think we can overcome anything.”
