77. Selena Gomez
Band Or Solo Artist?: Solo
Greatest Hit: "Love You Like a Love Song" (2011)
When you date Justin Bieber for two years, you know your hotness is on a different level than the rest of the general population. Before the Biebs, though, Selena got her big break in a starring role on Disney Channel's Wizards of Waverly Place. By 2008, she inked a deal with Hollywood Records. She has since released singles that have charted internationally, most notably her 2011 hit "Love You Like a Love Song" from her third album, When the Sun Goes Down.
Though her music career has been overshadowed by her acting career, she has made the transition from the cute girl next door to the hot superstar singer.
