America voted her into the top 12, and then kept voting for her week after week until she made it all the way to the show's finale, where she finished as runner-up. Shortly after the fifth season of American Idol was history, Katharine was signed to RCA Records. Her first single, "Somewhere Over the Rainbow / My Destiny," debuted at No. 2 on Billboard's Hot Singles Sales chart. On the Hot 100, Katharine became the first Idol singer to begin her chart career with two debuts in the same week, as "Rainbow" entered at No. 12 while "My Destiny" bowed at No. 60. Now Katharine is on tour with American Idols Live and is in the process of recording her first album. It's a destiny fulfilled. There was never any doubt about what I wanted to do with my life, she confirms. I always knew I wanted first and foremost to be a singer.
