Carrie Underwood is known around the world for many jobs, including international superstar, hit songwriter, Calia lifestyle and fitness brand mogul, and book author, but if you ask her five-year-old son, Isaiah, well, he's got a completely different answer. In an assignment for school which Carrie shared on Instagram yesterday (Thursday, Feb. 13th), Isaiah says that his mom's job is to "wash the laundry," and that his mom is really good at "folding laundry." Oh, and he also guesses her age is 70!

Along with a picture of the completed assignment, Carrie wrote, "Soooo…apparently I'm 70 and I'm really good at doing the laundry."

In her spare time away from the laundry room, Carrie has written a book called Find Your Path. The lifestyle and fitness book arrives on store shelves on March 3rd.
