Kelly Brianne Clarkson (born April 24, 1982) is an American pop rock singer, songwriter, and occasional actress. Clarkson made her debut under RCA Records after she won the highly-publicized first season of the television series American Idol in 2002. She was originally marketed as a pop musician with her debut album Thankful (2003). With the release of her multi-platinum second album Breakaway (2004), Clarkson moved to a more pop rock-oriented style of music. Clarkson's third album, entitled My December, was released on June 26, 2007. Her fourth album is due in fall 2008. Clarkson has sold over 20 million albums worldwide. Clarkson is the most successful American Idol alumnus. Eight of Clarkson's singles have become Top 10 hits on the Billboard Hot 100. In 2008, she joined Vh1's list of 10 sexiest women. She also hit #28 on Vh1's Top 30 Front Women.
Clarkson won the first season competition of American Idol on September 4, 2002, earning 58% of the audience vote over Justin Guarini. Choking back tears, Clarkson performed the ballad "A Moment Like This", the song written for the winner of American Idol, which would subsequently appear on her debut album Thankful. The song's music video was filmed at Pantages Theater in Hollywood, and incorporated short scenes of Clarkson performing on Idol. When released as a single in October 2002, it set a then record on the U.S. Billboard Hot 100 chart when it rose from number fifty-two to number one. This achievement was largely due to the impact from Idol as the CD single managed to sell 236,000 copies in its first week of sales in the U.S.; it spent five weeks at number one in Canada.
