Aww. We’re sure Isaac had an adorable message for his daddy, too, but he’s too little to type! Mostly, we’re proud of Kailyn for putting the past behind her and tweeting Jo such kind words.
They are both happily in relationships now — Kail engaged to Javi Marroquin and Jo dating Vee Torres — so we hope that one day, they will be able to celebrate their birthdays together. Hey, maybe there’s a double date in their future … or is it too soon?
Are you surprised that Kailyn wished Jo a happy birthday? Weigh in below.
