Born in Fort Worth, Texas and raised in the suburb of Burleson, Clarkson, the youngest of three children, first gained notice when she won the first season of the FOX singing show American Idol. Her first single, "A Moment like This", made history when it went from debuting at number 52 to going all the way to number 1 on the Billboard Hot 100, a feat she would accomplish again in 2009 when her song, "My Life Would Suck without You", went from number 97 to number 1. She has released 8 albums & has won 3 Grammy Awards. She has also had success in country music, having scored a top 10 hit with singer Jason Aldean on the song "Don't You Wanna Stay".
Clarkson first tried her hand at acting when she and American Idol runner-up Justin Guarini starred in the 2003 film From Justin to Kelly, which was a flop at the box office. She later said in an interview that the only reason she did the film was because of her contract with 19 Management. However, she has appeared in episodes of television shows such as American Dreams and Reba. She also provides the voice of Leah the horse in the 2017 animated film The Star.
Clarkson has written two children's books, River Rose and the Magical Lullaby, which was released in 2016, and River Rose and the Magical Christmas, which was released in 2017. The lead character in both books is named after Clarkson's daughter. There are plans to write more books.
Clarkson first appeared on the Voice as an advisor to Blake Shelton during season 2. She later was a key advisor during season 13. She had decided to be a coach on the Voice over being a judge on American Idol, which was relaunched on ABC, because she liked the Voice. She mentored the season 14 winner, Brynn Cartelli, becoming the first replacement coach to win in her first season & the third female coach to win.
