Jessa Duggar and Ben Seewald find out the gender of their baby on the next episode of Counting On.

Monday night's episode of Jill & Jessa: Counting On is set to include the highly anticipated reveal of the gender of Duggar and Seewald's baby. There is a new preview clip of the episode revealed on Us Weekly, in which Duggar, Seewald and other Duggar family members learn the gender of the baby.

"We decided that, just like last time, we're going to find out the baby's gender but not tell everybody," Jessa tells the camera in the clip. "But we did decide to let Jana and Joy come along with us and find out. So this is going to be a little bit of a different twist."

Jessa continues: "When my sisters heard we were going for an ultrasound, Jana kind of asked me, 'Hey, can I come along?' So we thought, 'Yeah, we can let Jana come along.' Well, then Joy was like, 'Hey, that's not fair. I want to come.' So we told them, 'Y'all can both come - just don't tell everybody.'"

Jessa is clearly excited in the clip, saying that both she and Seewald thought it would be a boy originally.

"We like to torture people. No, I'm kidding! It's just fun. ... We both guessed 'boy' when we found out we were expecting, but Ben changed his guess to a girl," she says. "The ultrasound is a really exciting time - you know there's a little life growing inside."

Jessa and Seewald already have one child - son Spurgeon Elliot Seewald - who is 1 year old. They are expected to have baby no. 2 in February. Jessa's sister Jill is also pregnant with her second child, which is due in July.

Jill & Jessa: Counting On airs Mondays at 10 p.m. ET/PT on TLC.
