Just two months after tying the knot (and sharing their first kiss!), Jill Duggar and husband Derick Dillard are expecting their first child.

The '19 Kids and Counting' star, 23, revealed the thrilling news to PEOPLE, telling the magazine: "We are so excited!"

While many of Duggar's pregnancy tests first came back negative, she tried one of her mom's -- and that turned up positive.

"It was surreal. We were shocked," Dillard, 25, said. "Both of us are so excited."

It's an excitement that undoubtedly extends to the entire Duggar clan.

"About 30 days after Jill and Derick got married they gathered everyone in the living room and shared the news," Duggar family patriarch Jim Bob revealed. "Everyone was clapping and cheering, and we were in shock, too."

The happy announcement follows just five days after the news that Duggar's younger sister Jessa will marry Ben Seewald.

Duggar and Dillard's child will join cousins Mackynzie, Michael and Marcus (the children of Duggar's brother Josh) as well as 18+ aunts and uncles.

Congratulations to the happy couple!
