Britney Jean Spears (born December 2, 1981) is an American singer. Often referred to as the "Princess of Pop", she has sold over 150 million records worldwide, making her one of the world's best-selling music artists. An influential figure in popular music, Spears became the best-selling teenage artist of all time, credited with the revival of teen pop during the late 1990s and early 2000s. After appearing in the television shows Star Search and The Mickey Mouse Club, Spears signed with Jive Records in 1997 at age 15. Her first two studio albums, ...Baby One More Time (1999) and Oops!... I Did It Again (2000), are among the best-selling albums of all time. She adopted a more mature and provocative style for her albums Britney (2001) and In the Zone (2003). Spears was the executive producer of her fifth studio album, Blackout (2007), often referred to as her best work. She returned to the top of the U.S. Billboard 200 chart with the albums Circus (2008) and Femme Fatale (2011), and embarked on a concert residency, Britney: Piece of Me (2013–2017), to promote her next two albums, Britney Jean (2013) and Glory (2016). Spears' catalog of high-charting singles includes "...Baby One More Time", "Oops!... I Did It Again", "I'm a Slave 4 U", "Toxic", "Gimme More", "Womanizer", "3", "Hold It Against Me", and "Scream & Shout". Spears' life, including her high-profile relationships and personal struggles during the 2000s, received widespread media coverage. In 2008, she was involuntarily placed in a conservatorship following a highly publicized breakdown. In 2019, her legal battle over her conservatorship led to the establishment of the #FreeBritney movement and a release of the documentary Framing Britney Spears (2021). The conservatorship was terminated in 2021, following her public testimony in which she accused her management team and family of abuse. Spears' 2023 memoir, The Woman in Me, reached number one on The New York Times Best Seller list in its first week of release. Her other ventures include starring in the film Crossroads (2002) and launching numerous products, with her 2005 fragrance Fantasy with Elizabeth Arden, Inc. generating over $1.5 billion in sales.

Billboard ranked her sixth on their list of the Greatest Pop Stars of the 21st Century. "...Baby One More Time" was named the greatest debut single of all time by Rolling Stone in 2020.
