With the Duggar family, you just never know what tricks they'll pull up their sleeves next. And that's why fans are wondering if sisters Jill and Jessa Duggar are planning a double surprise to keep their show on their air as the two reality television stars admitted that they plan on getting pregnant at the same time for their second time around.

According to People Magazine on Wednesday, the two mothers and wives made the revelation during Tuesday night's episode of Jill and Jessa: Counting On. Jill is already a mother to her 1-year-old son Israel David, who she shares with her husband Derick Dillard while Jessa's son with husband Ben Seewald, Spurgeon, was born last November.

When a producer asked during the finale episode, "Which of the two of you while have your second child first," Jessa answered coyly with, "It's hard to say."

Jill then responded with, "I think we will probably be pregnant at the same time. But to say who will be first, well Israel is older... so we will see."

What's more, Jill herself also put a stop to the rumors that she already has another bun in her oven.

She said, "I'm not pregnant yet, that's the question everyone keeps asking me," before Derick added, "I feel like we will have another child. I just don't know how. It will probably be a naturalized citizen of the family."

Jill and Derick are currently living in Guatemala as part of their missionary work while Jessa and Ben are living at home back in Arkansas.
