5. Katy Perry
When she wasn’t busy voicing Smurfette in this year’s reboot of “The Smurfs,” Perry spent most of 2011 watching her juggernaut of an album, 2010’s “Teenage Dream,” continue to smash records. It became only the second album in history to yield five No. 1 singles (joining Michael Jackson’s “Bad”) and kept Perry on the Billboard Hot 100 charts for a record-breaking 69 consecutive weeks. Now an established pop powerhouse, the California Gurl extended her reach into general diva-dom with a December hosting gig on “Saturday Night Live.”—Jeff Royer
