19 Kids And Counting patriarch Jim Bob's niece, Amy, 28, announced her engagement to boyfriend Dillon King on Instagram late last night.
"He loves the Lord, he makes me laugh uncontrollably, he's loyal, he's patient, he's my best friend. Of course I said yes!!" she told fans in a sweet post, complete with the hash tag #DillandDuggsforever.
She also showed off her sparkling new ring in the pic.
Amy's 27-year-old fiancé made a matching Instagram announcement, but also included photos of the proposal scene.
It seems the Arkansas printing firm owner popped the question on a romantic candle-lit trail in the woods.
"I got down on one knee because you are the only woman I have and will truly love forever!!!" he said.
Amy's embattled cousin Josh, 27, who's in the midst of a sex abuse scandal, was the first Duggar to publicly congratulate the couple.
"Congrats to Dillon & Amy on your engagement…welcome to the family @kingdillpickle!" the (almost) father of four said.
The engagement should come as no surprise to RadarOnline.com readers.
In an exclusive interview with Radar, Amy revealed that she and her boyfriend began shopping for rings together in the spring.
"We've looked around, and he knows what I like," the aspiring country singer said. "We're both committed."
But she confessed that she had "no idea" when her man would get down on one knee.
"I don't want to be involved in the actual engagement," she added, "so it's going to be a huge surprise!"
The couple began dating in November 2014 after five years of friendship.
