Jessica Simpson recently sang the Star Spangled Banner at Tiger Woods' Pro Am. Her boyfriend, Tony Romo, was paired with Tiger. Carrie Underwood, once upon a time, also dated Romo. Jessica gets really agitated about Carrie. I wonder why? Here's Jessica, honoring America by singing the National Anthem at the Tiger Tourney, and then Carrie, honoring America with the National Anthem. Do you have a favorite? If so, tell me in comments.
