"I'm just overwhelmed with emotion," the 19-year-old reality star's fiancé told Us Weekly. "I'm so excited to be engaged, because that means the next step is marriage, and I'm excited to see what the future holds for us!"
Joy-Anna announced she entered into a courtship with Austin last November, just a few days after sister Jinger Duggar's wedding to former soccer pro Jeremy Vuolo. The two have been close pals for nearly 15 years.
"This is my friend, Austin," she said in a video posted to the network's website at the time.
