Clarkson won the very first ever season of American Idol in 2002. She’s had several top 10 hits on the Billboard Hot 100. Her most notable hits are “Because of You” and “Breakaway.” Her single, “My Life Would Suck Without You,” broke the Billboard record for the biggest jump to the No.1 spot in chart history (from No. 97 to No. 1), during the first week it was released.
