It’s great to see Teen Mom 2’s Kailyn Lowry so happy these days — and a lot of the credit goes to her ever-supportive husband, Javi Marroquin. So of course we loved seeing Kailyn send her appreciation to her main man today on his big 21st birthday!

“HAPPY BIRTHDAY TO THE MAN I  MARRIED! @JaviM9,” Kailyn tweeted. “You drive me absolutely insane but I love you so much.” Aww! Could these two be any cuter?

Being a new parent can be tough on couples, and though Kailyn and Javi just welcomed their first son Lincoln to the world, they seem to be handling it all in stride. While we can't imagine the new father will be celebrating becoming legal the way the rest of us did, we doubt it's even crossed Javi’s mind. He’s got a happy and healthy family with Kailyn, Lincoln, and adorable stepson, Isaac — what else could you need?!

So what will these two get up to tonight? We’re not sure about this evening, but Kailyn did tweet earlier that she bought tickets for Disney on Ice for her and the boys, so that should be some good holiday fun for this young family. Seeing Mickey and Minnie do triple axels with your kids is way more fulfilling than overdoing it with shots at the bar. Plus, no hangover!

Happy Birthday, Javi!
