64. Demi Lovato
Biggest accomplishment this year: The renewal of her contract to judge The X-Factor when it returns for its third season
Demi Lovato has found second life as a judge on Fox's X-Factor, seeming downright normal when put next to Britney Spears. Her performance on the first season was well-received enough that she'll be returning next season with a doubled salary, not too bad considering she pulled in $1 million for her work last year. She also released her new album Demi in mid-May, and its lead single Heart Attack climbed as high as No. 10 on the Billboard Hot 100 chart. Lovato is also currently penning an e-book, which will be released in mid-June and will soon after join the literary canon as one of the great works of our time.
