Looks like Teen Mom 2's Kailyn Lowry and her husband, Javi Marroquin, are getting wet n' wild! This hot couple have been cuter than ever since Javi returned to Pennsylvania after six months of intensive Air Force training, and they spend every waking moment together.

Kailyn and Javi are expecting their first child later this year, and it looks like the bun in Kailyn's oven has made their relationship even stronger! In fact, these two are packing on the PDA like whoa — on land and at sea.

Check out this adorable picture of Kailyn and her man smooching underwater –– we're literally about to pass out from romance-overload.

"I told y'all I was a mermaid," Kailyn posted on Instagram along with the sweet pic. Aww!

It's no secret that Kailyn loves mermaids (she even has one tattooed on her arm!), and Javi is so Prince Eric to her Ariel. Which makes Kailyn's son, Isaac, Flounder, duh.

We can't wait for Javi and Kailyn to tie the knot for round two this Fall, and don't even get us started on how psyched we are about that baby in her belly!

Do you think Kailyn and her man are the cutest couple in Teen Mom Land? Spill your thoughts in the comments!
