Bio: Since coming to national attention on the second season of American Idol in 2003, Clay Aiken has evolved into a versatile and beloved popular entertainer. He has released five well-received albums and earned the distinction of being only the eighth artist to ever have his first four albums debut in the Billboard Top 5. In 2008, he began his critically lauded stint as the inept yet endearing Sir Robin in the Broadway musical "Monty Python's Spamalot." Prior to this, Aiken wrote a 2004 New York Times best-selling memoir, Learning to Sing: Hearing the Music in Your Life. He has been an ambassador for UNICEF since 2004 in addition to starting the Bubel/Aiken Foundation, which supports the integration of children with disabilities into the same environment as their non-disabled peers.
