Kailyn Lowry is sharing more details about why she left Teen Mom 2.

Two years after walking away from the MTV series, the reality star shared that her pregnancy with her fifth child, Rio—she shares the 23-month-old and 11-month-old twins Verse and Valley with fiancé Elijah Scott—inspired her multiple reasons to leave the show.

“Yeah, I left in 2022 when I got pregnant with my fifth son,” she told Trisha Paytas on the Oct. 17 episode of the Just Trish podcast, “because I was like, ‘I can’t, we’re not doing this.’”

The 32-year-old—who is also mom to sons Isaac Rivera, 14, with ex Jo Rivera, Lincoln Marshall Marroquin, 10, with ex-husband Javi Marroquin, and Lux Lowry, 7, and Creed Lopez, 4, with ex Chris Lopez—also revealed that she and her now-fiancé had not intended to have a baby at the time, which influenced her decision to leave.

“We did not plan to get pregnant,” Kailyn explained. “It was the first time I slept with him. And we had just developed a relationship. So, I was like, ‘This is just a lot for one person.’”
