Even though Leah Messer claims she has been faithful to her husband, ex-boyfriend Robbie Kidd told In Touch Weekly that he had sex with the “Teen Mom 2” star in October. Kidd originally said he and Messer were just friends, but now he says that she cheated on Jeremy Calvert.

The two spoke clandestinely for weeks until Kidd suggested they meet in person. “I asked her if she wanted to come over and talk,” he told In Touch, according to Radar Online. “Leah didn’t hesitate. She came right over, and one thing led to another and we had sex." "We wore protection," he added. The two reportedly haven't hooked up again, "That was the one and only time," Kidd told the magazine.

The claim isn't new. Cheating rumors exploded when Calvert, 25, accused Messer, 22, of infidelity on Twitter in October, which is the same time Kidd says he and Messer had sex. “Well that was a surprise kinda u did it to Corey and now me with the same person good job slut,” he reportedly tweeted. “Go back to Mingo and have a wonderful f---ing weekend with Mr. Kidd." The pipeline engineer soon deleted those tweets and eventually deleted his Twitter account.

But the fling between Kidd and Messer probably is not going to happen again since Kidd said he wants nothing to do with her. “I’m finally happy with where I’m at in my life,” Messer’s ex said. “We’ll always have a connection, but I’m tired of the drama.”

In earlier interviews, Kidd admitted he was going through a hard time personally and contacted the “Teen Mom 2” star, but said nothing sexual happened. “Whenever things are going bad in our lives, we reach out to each other, and this is what happens,” he said in the new interview with In Touch Weekly.

Kidd claimed Messer confided in him after she faced trouble in her marriage. “She said Jeremy doesn’t care about her or their family when he’s gone. All he wants to do is talk about sex,” he reportedly told In Touch Weekly. “Leah felt really alone because Jeremy’s gone a lot for work.”

Calvert reportedly wants to file for divorce and has already allegedly moved on with a new lady, Brittany Musick. She and Messer reportedly exchanged Twitter messages.

Messer originally said she would not appear in Season 6 of “Teen Mom 2,” but an exclusive report by Ashley’s Reality Roundup claimed that the West Virginia native signed up for another season because she needs the money.
