So how much of a Carrie Underwood fan are you really?

The 32-year-old pop-country superstar's career unfolded in front of our eyes ever since she was voted the winner of Season 4 of American Idol in 2004. In many ways, we feel like she's matured as an artist right before our eyes.

But Taste of Country has come up with some incredible facts that some of the most die hard Carrie Underwood fans might not already know about the Oklahoma native. For instance, did you know Underwood almost had a record deal before she joined American Idol?

It's true. And did you know that she worked at a pizza place while in college at Northeastern State University? Or that she was once booed while performing in neighboring state Nebraska?

Check out the video above from our friends at Taste of Country to learn more about the soon-to-be-mom!
