Clay Aiken may have come in second to Ruben Studdard in the second season of American Idol, but it was clear from the start that he had star power. His incredible singing range and warm personality garnered him many fans long before the season came to an end. He was even chosen to perform as the host of the American Idol tour that year. His first single made him the first artist in history to debut at #1 on Billboard’s Hot 100 chart and his first album went double platinum. The fourth most successful in record sales of all the American Idol alumni, he’s sold six million albums and had 11 sold-out national concert tours to date.
