Jim Bob and Michelle Duggar's 12th child Jason Duggar married his girlfriend Maddie Grace in front of 300 guests on Thursday at The Estate at Sweetwater Creek in Tennessee, People magazine revealed exclusively Friday.

The pair tied the knot and spilled all the details about their special day to the entertainment outlet.

Just having everybody together just to celebrate us, because you never get another day in your life where all of your loved ones are together," the newly minted Maddie Duggar told People, adding that "especially for us, because I'm from Tennessee, and so half my family lives in Tennessee and Kentucky, and then we're moving to Arkansas."

She told People the festivities were special because the happy couple was "able to see everybody in one place," telling the magazine, "It's just a big party where everybody gets together." The couple first met in December and got engaged in August.

Eight of Jason Duggar's 18 siblings were in the wedding party, according to People. Jedediah Duggar served as best man alongside groomsmen James Duggar, Justin Duggar and Jackson Duggar. The bridesmaid squad included the groom's sisters Johannah Duggar, Jennifer Duggar, Jordyn-Grace Duggar and youngest child Josie Duggar.

The duo met in the Instagram DMs in after Jason Duggar joked with his older sister Jana, who married her husband Stephen Wissmann in August, about settling down.

"I was talking with (older sister) Jana. I was telling her, I was like, 'Listen, Jana, you got to put yourself out there if you want to find a guy.' So I was like, 'Look, listen, I'm going to hop on here just to find someone, just to show you that I can do it," he told People. Maddie added: "Jase found my profile just because he accidentally tapped on the notifications button, he saw my profile picture. He was like, 'Oh, she's cute.' It was definitely a God thing though."

She told the outlet "there's no way we would've found each other. It was just crazy." And now, nearly a year later, the pair have tied the knot.

"I think for both of us, we're pretty simple people really. It's like just doing life together," Jason Duggar said. "Just being able to enjoy the next seasons of life and just be able to take those next steps."
