Demi Lovato has spent the past few weeks judging aspiring singers on "The X Factor," but on Sunday, the tables turned and she got to sing for a change. She belted out a beautiful rendition of the national anthem at Game 4 of the World Series in Detroit, where the San Francisco Giants beat the Detroit Tigers 2 - 0. Watch her sing it in the video clip above.
"So excited to sing the National Anthem at game 4 of the World Series tonight!!!!!" Demi tweeted.
Demi's no stranger to "The Star Spangled Banner." Last year, she sang it at Game 5 of the World Series, mostly to positive reviews.
