If one thing is for sure, Demi Lovato can sing, and we mean really sing! The "Confident" songstress belted out the national anthem at Citi Field for Game 4 of The World Series and she was actually incredible. She sang a cappella in her own version of "The Star Spangled Banner" and really showed off her vocal range.
Not only does this prove what a class act Demi really is but it also shows that she can sing anything. What a true talent!
