Fighting For Isaac! 'Teen Mom 2' Kailyn Lowry's Ex Jo Rivera Pushed To File For 50/50 Custody On Camera

Another battle for Kailyn Lowry!

In a sneak peek clip for Teen Mom 2, the mother’s ex and first baby daddy Jo Rivera, was urged to change their custody agreement of their son, Isaac.

“I don’t think it’s a good time to do that,” Jo told Vee, who suggested he fights for more custody. She explained, “I’m saying in the future, I’m not saying right now talk to her. I’m just saying she does a lot, she has school, she goes on vacations, she’s constantly depending on you to take him on extra days.”

Watch the heated conversation between the two in the clip above! Teen Mom 2 air Monday nights at 9pm ET only on MTV!
