Demi Lovato Sings the National Anthem at 2011 World Series

Demi Lovato blew away baseball fans at Game 5 of the World Series in Arlington on Monday with her rendition of the National Anthem. It was clear by her red jersey that the Dallas native was rooting for the home team to take the win, and she proved to be a good luck charm for the Texas Rangers, who won 4 to 2.

Lovato stood on the grass between home plate and the pitcher's mound smiling proudly as she sang. The packed stadium remained totally silent until she finished, but then erupted in a roaring cheer. True to form, the 'Unbroken' star hit every high note without skipping a beat or missing a lyric -- something Christina Aguilera could probably learn from.

In an interview at New York's Z100 Jingle Ball Kick-Off on Friday, Lovato shocked us all when she admitted that she owes her fans for snagging her the big gig. "They actually were the ones that landed me a spot in the World Series to sing the National Anthem," she said. "They basically hounded the MLB and Rangers team."

Those sound like the dedicated Lovatics that we know!
