Although this crooner was the runner-up on the second edition of American Idol, he went on to become one of the show's most famous stars. With his geeky appearance, his Southern charm and his powerful renditions of ballads such as "Bridge Over Troubled Waters," Aiken won the hearts of viewers and spawned a veritable cult of rabid fans (Claymates) that turned him into a best-selling pop star. "This Is the Night," his 2003 debut single, sold more than 392,000 copies during its first week, breaking the previous record set by Elton John's "Candle in the Wind 1997," and Aiken's first album, Measure of a Man, debuted at No. 1 on the Billboard album chart and went triple platinum. In 2004, the sudden star was a busy boy, making the rounds on the talk-show circuit, publishing a memoir, touring all over the country, and even producing and appearing in his own eponymous Christmas special and releasing an accompanying album. Aiken kept a lower profile in 2005 (although he did a guest spot on the sitcom Scrubs) and didn't release his next album — A Thousand Different Ways, which was mostly covers — until September 2006. He made his Broadway debut in Spamalot in 2008, welcoming a son with friend Jaymes Foster (sister of music producer David Foster) later that year. In 2010, Aiken reunited with his American Idol cast mate Ruben Studdard for summer tour. Out of the spotlight, the singer is an advocate and fund-raiser for children with disabilities.
