Kelly Clarkson is the "O.I." (Original "Idol"), and it's quite possible no subsequent "Idol" will ever compare. This first-season champ has sold 19 million albums worldwide (including 12 million copies of her sophomore effort, "Breakaway"), won two Grammys (even beating out Paul McCartney!), scored three #1 pop singles, and is the most successful "American Idol," in the international marketplace. Until recently, it seemed like nothing could derail Kelly's post-"American Idol" career, not even her straight-to-video flop film "From Justin To Kelly"... until she battled BMG honcho Clive Davis for artistic control of her third album, the largely self-penned "My December." Amid the flak she received for that controversial business decision (which coincided with the firing of her manager and cancellation of her tour), "My December" unfortunately sold poorly compared to her previous monster-hit albums. However, the critical praise it received proved that Kelly -- still the second most successful "Idol" ever -- is a true artist. She's here to stay and surely has much success ahead of her.
