Sounds Like: Before his voice changed? Lady Gaga. After, David Grey.
Notable Achievements: The little boy from that Ellen video has proved that not all viral fame has to disappear after 15 minutes. Two-and-a-half years after his talent-show performance of “Paparazzi,” Greyson Chance has weathered the vocal turbulence of puberty and emerged as a capable adult-contemporary performer. (Check out his rollicking cover of Adele’s “Rolling in the Deep.”) He has also broken into acting in his spare time, guesting on the second-season premiere of Raising Hope.
Famous Fans: Ellen Degeneres gave Chance his, well, chance, and Miranda Cosgrove gave him an opening spot on her 2011 tour. He has also proven to be amazingly popular in Asia.
