9. The most powerful celebrity of 2012 is Jennifer Lopez — Jenny From The Block may have been way more famous back in the early '00s, but the girl's grown up, diversified her skill set, and has proved she can be as big — nay, bigger a mogul than anyone else out there. After experiencing a few musical and creative setbacks (Gigli, anyone?), J. Lo has come back with $52 million in earnings last year (via her clothing line, fragrance sales, spokesperson gigs, as well as a stint as a judge on American Idol). Thanks to all of that, J. Lo topped Forbes' list of the most powerful celebrities of the year, beating out Oprah and Justin Bieber.
