Unsigned singer/pianist Christina Grimmie's story may have started as a small child with a karaoke machine, but over the last year and half, it's found an audience through YouTube.
Grimmie is overtaking her big-name competitors -- including Justin Bieber and Rihanna -- in the My YouTube contest. As of Feb. 2, the 16-year-old held the lead with 153,000 fan votes. Next up was Selena Gomez, with 150,047. Rihanna counted 106,931 votes while Bieber, who first made his mark on the video-sharing site, had tallied 102,000 fan votes.
The My YouTube competition kicked off on Dec. 8, 2010, and ends Feb. 7, with the top five artists gaining massive exposure through placement on YouTube's U.S. and international home pages. Fans drive the votes by subscribing to artist channels, as well as other channels recommended by the 50 acts that YouTube asked to participate.
