30. Nicole Scherzinger
Say what you will about the artistic merit of this former Pussycat Dolls leader, Sherzinger is a beauty with the will to claw her way to the top. So far, that has meant wading her way through the jungles of reality TV, first as a contestant (and eventual champion) of “Dancing with the Stars,” then as a judge on the a capella show “The Sing-Off,” and now most famously as a judge on “The X Factor.” Meanwhile, she’s stubbornly plugging away at that singing career – she even released a solo album earlier this year called “Killer Love” that, like the rest of America, you probably heard nothing about. You’ve got to admire her tenacity.—Jeff Royer
