A nod to her baby boy? Pregnant Jill Duggar showed off her baby bump in a blue tight-fitted dress while taping an episode of Extra with her husband Derick Dillard on Thursday, Oct. 23.

The expectant parents looked smitten with each other during the NYC taping. Duggar, 23, cradled her growing belly, which was accentuated by a thin brown belt.

The 19 Kids and Counting stars announced earlier this week that they are expecting a boy. Last month, Duggar exclusively told Us Weekly that she took three pregnancy tests before finding out she was going to be a mom.

"We were really surprised when we got that positive test," Duggar said at the time, explaining that the first two came out negative. "But of course we were really excited. I think we would have even been less surprised had it come back positive on one of the first tests."

Duggar and Dillard, 25, are over the moon about expanding their family. So much so that they've already registered for their little guy. Some of the items on their wish list include pacifiers, blankets, bedding, a Fisher-Price Jumperoo, and a jogging stroller.
