Andrea is a former vocal student and used her talents to share the news by showcasing her adorable kids and their somewhat chaotic household, with the little tots splashing in the pool, making a mess of their bedroom and having fun with full boxes of cereal.

Andrea told INSIDE EDITION, "The whole idea came from me saying to a friend, 'We can't seem to stop' when we found out we were unexpectedly pregnant."

A live chicken joins in the fun at one point where the Chapman's prove that chickens can fly.

"What was just intended as something funny for our friends and family has really resonated with people who have large or in any way, unusual families -- families who have adopted or who don't look like the perfect mom, dad, 2.5 kids. It's YOUR family and you can do what you want to," said Andrea.

We can only imagine what their next announcement will be like.
