Jill Duggar and her husband Derick Dillard are expecting a baby boy.

The "19 Kids and Counting" stars told People Magazine that they will welcome a baby boy in spring of next year. The announcement comes two months after they revealed that Jill was pregnant.

"I was really excited," Derick told People. "As a new dad, to have a firstborn son to be our first child and be the leader of his siblings, it is very special." 

The couple were accompanied by Jill's siblings - Joy, 16, James, 13, and Jenny, 7, - during their gender-revealing ultrasound Saturday. Jill told People that each sibling had their guesses on whether she would be having a boy or a girl.

"Oh yes, there was some screaming in the room," the 23-year-old mom-to-be recalled. "I thought all along we were having a girl. Everyone made their guesses. My mom and dad both thought it was going to be a boy and my grandma did, too. They are all really excited." 

The night before her ultrasound, Jill said she was "praying for a big, healthy baby." Before her big appointment, she ate fruits, waffles with syrup and whipped cream and drank chocolate milk and lemonade.

"We could have a giant," Jill said about her baby. "I called Derick's mom and she was telling me that when Derick was born, he didn't fit into the newborn clothes and his shoes were a size two."

As for baby names, Jill said she isn't too sure if she will follow in her parents' footsteps and have a letter theme, but added that she and Derick "may do some kind of theme, like family names."

Last month, Jill took to Instagram to announce that she had entered her second trimester. She is currently 18 weeks pregnant, and the couple are prepping for the arrival of their baby boy with shopping for clothing and baby supplies.
