With a birthday message this touching, we can only imagine how emotional Josiah Duggar's vows will be on his wedding day! The 21-year-old reality star shared an Instagram post to honor his fianceé Lauren Swanson on May 18, and it's totally heartwarming. Watch the video above to see the entire sweet message!

Today is Lauren's 19th birthday, and we're sure there's no way she'd rather spend it than with Josiah. The couple announced their engagement in March, three months after revealing that they were courting in January. However, there was proof that Lauren and Josiah had been seeing each other for several months before that.

They've been practically inseparable since they announced their courtship, and Josiah seems genuinely in love. "I’m really enjoying the beauty in New Zealand. ? Oh, and the landscape is pretty nice too I guess. ?," he captioned a pic with Lauren in January, along with "#mygirl." The day before her birthday, Josiah posted another beautiful photo with his lady with the caption, "Happiness is anywhere with you by my side." So cute!

Josiah definitely seems to respect Lauren more than some of the Duggar womens' husbands, and it seems like they've decided to do things their own way. For example, Lauren and Josiah hold hands all the time, and post photos cuddling. Plus, Lauren often breaks the Duggar modesty rules, showing off her knees in shorter skirts, and Josiah supports her completely. Do you, guys, we're living for it.

Fans are obsessed with the sweet due. "This is beautiful!! What a great and loving man Lauren has ??," said one fan. "Happy birthday Sweet Girl! I hope he is treating you like a queen," said another. That definitely seems like the case, judging by the photo of the couple smiling on the beach!
