Since it was their third pregnancy, Jill and Shawn decided to wait until 20 weeks to find out their baby's gender. They even invited Jill's sister Kelly along, and she absolutely lost her shit when it was revealed that they were having TWINS!

After a long, careful look, Kelly finally saw something!
