Kailyn Lowry has kept her third baby daddy out of the spotlight – but that doesn't mean he's out of her life! Breaking Celebrity News can exclusively reveal how involved the mystery man has been in the Teen Mom 2 star's pregnancy.

"He's been there whenever Kail has needed him," a source close to Lowry, 25, told Breaking Celebrity News. "He is supportive of her so it's been good."

Lowry's baby daddy even plans on being involved when the baby is born.

"Co-parenting when the baby is born is the plan as of now," the insider said. "They're working on things currently to get back together."

As for the mother of Isaac, 7, and Lincoln, 3, her third pregnancy has been "rough."

"She's pushing through it," the source said. "She's really excited to meet her new addition."

Breaking Celebrity News exclusively broke the news that Lowry is expecting her third child in February.

Hours later, the MTV star confirmed the pregnancy on her personal blog.

At the time, a rep for Lowry told Breaking Celebrity News the father is a man she "briefly dated."

"We don't know how involved the father will be," the rep said. "Kail will release that information when she's ready."

Lowry accidently revealed the first name of her baby daddy during an Instagram live video.

When a user suggested she name the child Holden, Lowry joked, "Chris would say, I'm Holden the baby!"
