'19 Kids and Counting': The Big Revelation

The cast of the "19 Kids and Counting" on TLC are already expecting their first child. Ahead of their wedding debut on TLC and Jill's celebration of 18^th week pregnancy, the couple confirmed the gender of their baby Tuesday.

The reality-TV couple are expecting a boy, according to People.

"I was really excited," Derick, 25, said of the gender news. "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 already learned the gender of their child through an ultrasound last Saturday with three of Jill's siblings and co-stars in attendance. Her parents, Michelle and Jim Bob, were not in the room during the big reveal of the baby's gender.

"There was some screaming in the room," Jill, 23, said in recalling the ultrasound. "I thought all along we were having a girl. Everyone made their guesses. ... My mom and dad thought it was going to be a boy and my grandma did, too. They are all really excited," Jill added.

According to the longtime TLC star, her unborn child already takes after her accountant husband. 

"He stretched out his legs full length. He was trying to be like Dad," Jill said. "We could have a giant. 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," Jill added.

After the revelation of their baby, Jill said she's thinking of the perfect name for the baby. Unlike her family's "J" name theme, Jill said she will not give her future offspring identical initials.

Jill and Derick got married in support of their more than 1,000 family and friends in Springdale, Arkansas, in June after several months of courting stage.

Jill also added that she was a little bit shocked of her pregnancy. Jill, who is due in March, is the first Duggar family daughter to marry and produce a grandchild. Her brother, Josh, wed his wife Anna in 2008. The couple now has three children.
