It's Time! Inside Kailyn Lowry's Dramatic Delivery

The final star of the Teen Mom 2 baby boom is only days away from giving birth! Kailyn Lowry revealed over Twitter that she has had her final doctor’s appointment before she welcomes her third child. RadarOnline.com can reveal exclusive details on how her ex-husband Javi Marroquin will be involved with the big day.

“One more appointment today,” Lowry, 25, tweeted. “Getting closer & closer.”

The mother-of-two is expected to give birth this month with ex-boyfriend Chris Lopez.

As RadarOnline.com reported, Lopez left her around the time she learned she was expecting and has not been involved in her pregnancy.

“Kail became a relationship of convenience for him,” a source close to Lowry told RadarOnline.com. “He never actually loved her. It was a relationship, but he just decided he wanted something different and things didn’t work out so they went their separate ways.”

Although his involvement in his child’s life is up in the air, Lowry will reach out to him when she goes into labor.

“She wants to give him the opportunity to see his child being born,” the insider said. “She never said Chris couldn’t be involved with his child. She would hope he would want that, but she won’t force it or chase him to do so.”

But Lowry will have one man she could depend on, her ex-husband Marroquin.

The father of Lincoln, 3, exclusively told RadarOnline.com that he has worked out “plans for all scenarios” for when she gives birth regarding who will care for their son.
