Kelly Clarkson is an American singer, songwriter and television personality. She rose to fame in 2002, after winning the first season of American Idol, which earned her a record deal with RCA Records. Clarkson's debut single, "A Moment Like This", topped the US Billboard Hot 100 chart and became the country's best-selling single of 2002. It was followed by the release of her debut album, Thankful (2003), which debuted atop the US Billboard 200. Clarkson shifted to pop rock music for her second album, Breakaway (2004). After numerous top 40 radio number-one singles, such as "Since U Been Gone" and "Because of You", the album sold over 12 million copies worldwide and earned Clarkson two Grammy Awards.

She took further creative control for her third album, My December (2007), by becoming the executive producer and co-writing the entire album. Clarkson returned to the top of the charts with her fourth album, All I Ever Wanted (2009). Its lead single, "My Life Would Suck Without You", holds the record for the biggest jump to number one on the Hot 100 chart. Her fifth studio album, Stronger (2011), made Clarkson the first artist to win the Grammy Award for Best Pop Vocal Album twice. It spawned her third Hot 100 number-one single "Stronger (What Doesn't Kill You)". She became the first American female artist to achieve the best-selling holiday album of the year with Wrapped in Red (2013). Following the release of her third number-one album Piece by Piece (2015), her soul-influenced eighth album, Meaning of Life (2017), hit number two on the Billboard 200 and garnered her a record fifth Grammy nomination for Best Pop Vocal Album.
