Babies are popping out left and right over in Kailyn Lowry's neck of the woods, and the latest lady to give birth? No, not Kailyn (though she wants to have another baby sometime soon), we're talking about her sister-in-law, who just welcomed an adorable little boy into the world!

Yep, this means that Kailyn is officially an aunt, and she took to Twitter to express her excitement. "I'm an AUNT!" Kailyn tweeted on May 27. "Congrats to my sister and brother-in-law on the birth of their healthy baby boy!"

Kailyn's brother-in-law is none other than Sal Marroquin, aka her husband, Javi Marroquin's brother — who Kailyn's formed a close bond with. As far as we can tell from this insanely-cute photomontage of Sal's new baby, he was born healthy on May 27, and his name appears to be Lil' Sal until further notice. And yes, you better believe Javi is just as psyched as Kailyn.

"My nephew/godson was born today!" he tweeted. "Another cousin for the boys."

Aww, how sweet! Javi is clearly pumped that his son, Lincoln, and step-son, Isaac, have another baby cousin to play with. We're so happy that Kailyn has finally gotten everything she wanted out of life: a big, happy family full of love and crazy-cute kiddos.
