Kailyn Lowry and Javi Marroquin’s relationship has been a central narrative in the Teen Mom franchise. The couple met in 2011 and married in 2012, later welcoming their son, Lincoln, in 2013. Their marriage, however, faced significant challenges, including allegations of controlling behavior and a miscarriage in 2015, which strained their bond. They finalized their divorce in December 2016. Despite their separation, they have continued to co-parent Lincoln, navigating the complexities of their relationship in the public eye.

Recently, Javi expressed concerns over Kailyn’s new relationship with Isaac Knighton, criticizing her for introducing a new partner so soon after her breakup with Elijah Scott. In light of Javi’s tearful Instagram rant, Kailyn took to her Instagram Stories to address the situation.

“I’m seeing the comments. I see everything that’s being posted right now, and I’m going to address it at a later time,” Kailyn posted to her Instagram Stories on June 4, 2025.

She noted that she wanted to focus on her 15-year-old son, Isaac Elliott Rivera. The former Teen Mom recorded a new podcast episode with her son.

“But this week was dedicated to Elliott, and it’s super important to him and to our family to keep things as planned,” she continued via Instagram Stories. “And I’m not going to take this moment away from him. So, I would just love for everyone to support my son and what he has to say, and let him share his story this week. And I will address everything at a later time.”

Who is Kailyn Lowry’s new boyfriend, Isaac Knighton?

Teen Mom star Kailyn Lowry has a new man following her breakup with Elijah Scott in April 2025. Kailyn and Elijah parted ways after rumors surfaced claiming Elijah cheated while on a cruise ship in May 2024.

So, who is Kailyn’s new boyfriend, Isaac Knighton? According to The U.S. Sun, he’s a fishing enthusiast who dubbed himself “The Flyest Fisherman.” Isaac is also a former Northampton Community College student from Allentown, Pennsylvania.

The couple’s relationship quickly garnered attention, especially after Isaac posted a video of them kissing in January, signaling a more serious commitment. However, their romance has faced scrutiny, notably from Lowry’s ex-husband, Javi Marroquin, who expressed concerns about their son Lincoln being introduced to a new partner so soon after the breakup.

Javi Marroquin slammed his ex for bringing Isaac Knighton to Lincoln’s sporting events

Javi Marroquin didn’t hold back when slamming Kailyn Lowry on Instagram Live. He said the Teen Mom star showed up late to their son’s sporting event — and she brought Isaac Knighton with her.

“Shows up this past weekend with a new boyfriend,” he said. “Shows up 40 minutes late to practice to show up to practice with this guy.”

He then addressed rumors that Isaac is already moving in with Kailyn.

“Word on the street, allegedly, is this man is moving in,” Javi continued. “This man has sold his stuff in Pennsylvania to move to Delaware. … So, you’re telling me my son cannot come with me because he’s better off with you? How does that make sense? And I’m sick of it.”
