It looks like Teen Mom 2 star Javi Marroquin is finally coming around when it comes to Kailyn Lowry being pregnant.

Although they announced their split in May and finalized their divorce in December, Javi — a member of the United States Air Force — seemed far from pleased at first when his ex revealed that she is expecting her third child. She also admitted that while she told her ex-boyfriend and first baby daddy, Jo Rivera [who she shares seven-year-old Isaac with] about the new baby, she did not have the same conversation with three-year-old Lincoln's dad.

Instead, Javi found out thanks to little Linc.

"Lincoln is actually the one who told me she was having a baby. He knows what's going on. He's excited to have another sibling," he told E! News. "I'm happy for Kail. I wish her nothing but the best and health and wellness and all of that stuff you know? I'm here for her. We actually are in a good place and I just want health for her and the baby."

Kailyn's new baby will be here by summer, though we are still unaware of the gender or father at this time. Some potentials include Tyler Hill, JC Cueva, and most recently Chris Lopez.

Javi moved on from their split with Cassie Bucka and is now dating The Real World: Skeletons alum Madison Channing Walls.

"Kail knows about the relationship for sure," he explained, adding she has yet to meet his son.

"I learned from my past mistakes where I introduced him way too early on in a relationship, so now I know better."
