Demi Lovato Sings National Anthem at MLB World Series Game 4 (@DDLovato)

X-Factor Judge and Multi-Platinum Recording Star Demi Lovato proved she knows what the X-Factor is last night, because she’s go it! Demi got asked to sing the National Anthem before last nights MLB World Series Game 4, which came to be the final game of the Series with the Giants sweeping 4-0, and coming out World Champions.  Demi’s voice is so sweet at first and then she brings it, really brings it, and shows off her vocal range about halfway through the song. She killed it last night, if you missed it, check out the video!
