Well Teen Mom 2 fans probably never thought they’d see the day!

For much of Kailyn Lowry’s four-year marriage to Javi Marroquin, the Airman took issue with her ex Jo Rivera (who happens to be the father of her six-year-old son, Isaac).

So that could explain why fans were so surprised to see the two men (and Jo’s fiancée, Vee Torres) hanging out!

The timing should come as no surprise — as Kail is currently vacationing in Hawaii!

As the Twitter account notes, all the kids — Isaac, Kail and Javi’s son Lincoln, and Jo and Vee’s daughter Vivi — were in attendance, so we think this is an awesome to keep things as “normal” as possible for Isaac in the wake of the divorce.

We love seeing this “modern family” come together!
