Kailyn Lowry is setting the record straight.

The star of Teen Mom 2 has addressed a “fan theory” that claims she had an abortion rather than a miscarriage when pregnant with her third child.

“That is honestly the worst thing I’ve ever read about myself. So hurtful and untrue… What a theory,” she tweeted. She later added, “Most of the time I don’t say sh-t. But this morning was some serious sh-t that just isn’t OK.”

Some fans started a rumor after theorizing that Kail cheated on her now ex-husband, Javi Marroquin, and terminated her pregnancy because the baby was another man’s.

As fans know, Kail and Javi were expecting her third child together late last year when she unexpectedly lost the baby. The miscarriage was one of the many reasons their marriage began to crumble — partially because Kailyn felt the need to put their baby plans on hold rather than trying again immediately, and partially because Javi “blamed” his then-wife for losing the baby.

In one episode, Javi told her, “You know how much I wanted that baby.”

At the time, she explained that she didn’t want to try for No. 3 because their relationship was already in trouble and she feared the possibility of being a single mom to three if the marriage ended in divorce (which, we all know now, it did).

At a reunion special, she later expressed her frustrations to Dr. Drew that she didn’t feel at all supported by her husband when they lost the baby. She explained that he “blamed” her for losing the baby, adding, “He was not helpful, he was not sympathetic.”

Javi attempted to justify his feelings.

“In my mind, I knew it wasn’t her fault. I was just hurt and I took it out on her — that was my mistake,” he said. “That’s where our marriage kinda started to go downhill.”
