Britney Jean Spears, the "Princess of Pop", is arguably the most iconic and talked-about pop stars of the last three decades. After her first two albums (1999's Baby One More Time and 2000's Oops!... I Did It Again) sold close to 40 million copies together, she established herself as the most successful teenage performer of all time thanks to her brand of accessible bubblegum pop, with her subsequent and more R&B/hip-hop-tinted releases, 2001's Britney and 2003's In The Zone, evolving her sound and maturing her image while keeping her success alive. During an uncertain period in her life in 2007, she released the electronic Blackout, often considered one of the most influential pop albums of the century, to a strong commercial response and returned to the top of the charts with 2008's Circus and 2011's Femme Fatale, both electropop releases that featured some of her most successful singles overall. A mixture of personal issues have kept her career somewhat slowed down, with her last albums (2013's trendy Britney Jean and 2016's mellower Glory) failing to reach her previous commercial heights, albeit for very different reasons, despite some of the best reviews in her career for the latter.

Britney created The Britney Spears Foundation, for children in need, in 2001 and donated over a million dollars through the foundation for children of 9/11 victims, but closed it down ten years later for her personal life issues. She has also released 26 perfume fragrances that has sold over 50 million bottles worldwide, 2 videogames (a console game in 2002 and a mobile game in 2016) and her own doll line. She made her acting debut in the 2002 film Crossroads to mixed reviews to her performance, and has also appeared in TV shows like How I Met Your Mother and Glee; she was a cast member of The Mickey Mouse Club between 1993 and 1994.

During her career, Britney has sold over 100 million records worldwide, reached the summit of the Hot 100 in three different decades, and was awarded with a Grammy Award, 6 MTV Video Music Awards (including the Michael Jackson Vanguard Award), 7 Guinness World Records, 7 Billboard Music Awards (including the Millennium Award) and a GLAAD Media Award's Vanguard Award.
