'Teen Mom 2' Sneak Peek: Kailyn Wants To Extend An Olive Branch To Jo And Vee

As the young mother plans a birthday bash for her son Isaac, she ponders inviting her ex...and his girlfriend.

Kailyn's son Isaac is getting older and she's doing her best to show him that his mom and dad can get along, even though they're with other people. Case in point: On tonight's episode of "Teen Mom 2," the mother of two is thinking about inviting her ex Jo and his girlfriend Vee to Isaac's fourth birthday bash.

In the sneak peek below, Kail goes out to eat with two pals and tells them her plan.

"Do you think they'll come?" one friend wonders.

"We'll see. I hope they do," Kail responds. "For Isaac, I hope they do."

When asked if she is on better terms with Jo and Vee, Kail admits that it took a lot of time for her to accept Jo's new relationship.

"I didn't like her in the beginning because I wasn't over Jo -- or like I was, and I didn't want anyone else to have him," Kail explains. "It's going on two years with her. And I just feel like at this point, I need to move on. I need to make amends with her."

+ Will Kailyn extend the invitation to Jo and Vee, and if so, will they attend Isaac's party? Watch tonight's new episode of "Teen Mom 2" at 10/9c to find out.
