27. Demi Lovato
The Disney starlet proved herself to be a survivor this year, first by admitting she needed help for the issues that sent her to rehab, and secondly by emerging stronger and more confident than before. Her new album, “Unbroken,” which documents her struggles, yielded Lovato’s first Top 10 hit, “Skyscraper.” I get the feeling it won’t be the last we hear of Demi Lovato 2.0.—Jeff Royer
