Teen Mom 2's Kailyn Lowry Wants Jo Rivera Back…And Another Baby

Earlier this year, Kailyn was going steady with Jordan Wenner. But the source reveals the 19-year-old mom was anything but a faithful girlfriend — getting frisky with Jo on the side!

“Jo was spending time with her and their son, Isaac, and basically one thing led to another,” the source says. “Kailyn cheated on Jordan, and Jo cheated on his girlfriend, Vee.”

Kailyn and Jordan parted ways soon after, allowing the Teen Mom to pick things up again with her ex. “When Kailyn and Jordan broke up, she and Jo got together again,” the source says. But the mom of 23-month-old Isaac may not be ready to jump back into things with Jo immediately.

“Kailyn is a bit torn now,” the source says. “Jo plays games with her. But if Jo broke up with his girlfriend and then said he wanted to be with Kailyn, she’d do it.” More than anything, Kailyn would like for her son to have a support system.

“She wants Jo, Isaac and her to be a family,” the source says. “She never had a family like that growing up, and she wants that for her son.”

As for a wedding, “Kailyn sees marriage as forever,” the source says. “She feels like you can’t turn back from it, so you can’t go into it lightly.”
