Demi Lovato Sings 'Star-Spangled Banner' Before World Series Game 4

While the San Francisco Giants and their fans were celebrating their World Series triumph over the Detroit Tigers on Sunday, pop star Demi Lovato was rejoicing for a whole different reason.

The "Skyscraper" crooner sang "The Star-Spangled Banner" before the start of Game 4 in front of live audience at Detroit's Comerica Park, and the absence of any major hiccups mean that she did a fine if not a spectacular job. While performing the national anthem (without mistakes) shouldn't be a major achievement for a professional singer, the baffling history of blunders associated with this particular gig meant that Lovato was lauded for her error-free rendition.

Before taking the centre of the field, she tweeted: "So excited to sing the National Anthem at game 4 of the World Series tonight!!!!!"

The 20-year-old, who was introduced as the X Factor judge, dressed casually for the occasion and wore a t-shirt that had the word "LOST" imprinted on the front. She did get a little 'lost' while belting the high notes of the tune but other than that, it went quite smoothly.

Some of the listeners, however, didn't like the unnecessary 'soul' in the song and thought that Lovato oversang some of its parts. It should be noted that she had sang "The Star-Spangled Banner" before the Game 5 of the 2011 World Series too, and its simplicity was liked by the listeners.

Here are both the 2011 and 2012 versions of Demi Lovato's US national anthem:
