As the second season of Fox's "X Factor" debuted last week to less-then-stellar ratings, all eyes were on its erratic new popstar-turned-judge Britney Spears, whose public appearances in recent years have been infrequent and notably awkward, if not completely disastrous. But this week, as the show's ratings improved and Britney proved to be positively boring, the singing competition show's other new judge, 19-year-old Demi Lovato, surfaced as a clear standout. Young, precocious and rounded out with a troubled back story of her own, Demi established a feisty rapport with fellow judge Simon Cowell that the show's editors clearly love. Combine that with the fact that she has a hit song in the form of "Give Your Heart A Break" -- and a built-in tween fan base thanks to her early years in the Disney stable -- and it's no wonder Demi is experiencing such a surge in popularity, on Twitter and on the radio. You can bet it isn't teen boys who drove "Awww Demi" to the top of the trends list this week, and for a young female star to leverage that wattage of girl power speaks volumes about her unique place in the hearts of a Twitterverse packed with Beliebers and One Directioners.
