Happy birthday, Kai! Jenelle Evans' second son, Kaiser Griffith, got what might be the best birthday present one of the Teen Mom kiddos could ask for—both his parents putting their differences aside and reuniting for his first birthday party.

The tot, who officially turns one on June 30, celebrated the big bday on June 21 with a Finding Nemo-themed party thrown by his mom, Jenelle and with assistance from big brother, Jace, of course.

And because an underwater-inspired smash cake and a pool all to himself isn't enough for the big guy, Kaiser got to spend a little time with both of his parents!

Considering the birthday party was held on Father's Day, it makes sense that Nathan would attend his big guy's big day. The couple officially split in April and have reportedly had a no-contact order in place since March, when Nathan got arrested on domestic violence charges, but we're happy to see that that's long gone and that J and N are co-parenting nicely.

"Even though we have our ups and downs one thing will never change... U are and always will be a great father," Jenelle captioned this photo of Nathan and his mini me.

While Jenelle currently has custody of Kaiser (though the one-year-old sees his dad often, too), Jenlle will fight her mom, Barbara, for full custody of her older son, Jace on the new season of Teen Mom 2 which premieres in just two weeks on Thursday, July 9 at 10pm on MTV!
