Start counting! Just two months after tying the knot, 19 Kids and Counting star Jill Duggar is pregnant, expecting her first child with husband Derick Dillard.

The married couple announced their exciting news on Wednesday, Aug. 20. TLC confirmed Jill's pregnancy in a release, with a representative adding that the network is "thrilled" for the newlyweds. The mother-to-be, 23, is the fourth oldest of the expansive Duggar clan, with two older brothers, an older sister, and 15 younger siblings.

Jill will be the second Duggar child to start a family of their own. Her older brother Josh and his wife Anna are the parents to three children.

Jill and Derick, 25, started getting to know one another in August 2013, when the Duggar patriarch Jim Bob connected his daughter with the potential suitor.

"When my dad first introduced Derick and I, we spent hours texting, calling, and talking on Skype," Jill said this past April, when she announced she and Derick were engaged. "We knew within days that we wanted to spend the rest of our lives together."

The reality TV couple said "I do" on June 21 in Arkansas. "I love Derick's desire to follow God and to serve others," Jill said of her husband. "Derick is so romantic."

Derick and Jill's baby will have a new uncle, as Jill's sister Jessa got engaged to her boyfriend Ben Seewald just last week.
