Kailyn Lowry has kept her third baby daddy out of the spotlight – but that doesn't mean he's out of her life! RadarOnline.com 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 RadarOnline.com. "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."

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