Britney Spears

Spears was executive producer of her fifth studio album Blackout (2007), often referred to as her best work. Following a series of highly publicized personal problems, promotion for the album was limited, and Spears was involuntarily placed in a conservatorship. Since then, she released the chart-topping albums, Circus (2008) and Femme Fatale (2011), the latter of which became her most successful era of singles in the US charts. She embarked on a four-year concert residency, Britney: Piece of Me, at Planet Hollywood Resort & Casino in Las Vegas to promote her next two albums Britney Jean (2013) and Glory (2016). In 2019, Spears's legal battle over her conservatorship became more publicized and led to the establishment of the #FreeBritney movement. In 2021, the conservatorship was terminated following her public testimony in which she accused her management team and family of abuse.

Regarded as a pop icon, Spears has sold over 100 million records worldwide, including over 70 million in the United States, making her one of the world's best-selling music artists. She has achieved six number-one albums on the Billboard 200 and four number-one singles on the US Billboard Hot 100: "...Baby One More Time", "Womanizer", "3", and "Hold It Against Me". The "S&M" remix also topped the Billboard chart. Her singles "Oops!... I Did It Again", "Toxic", and "Scream & Shout" topped the charts in most countries. With "3" in 2009 and "Hold It Against Me" in 2011, Spears became the second artist after Mariah Carey in the Hot 100's history to debut at number one with two or more songs. Her heavily choreographed videos earned her the Michael Jackson Video Vanguard Award. She has earned numerous other awards and accolades, including a Grammy Award, 15 Guinness World Records, six MTV Video Music Awards, seven Billboard Music Awards (including the Millennium Award), the inaugural Radio Disney Icon Award, and a star on the Hollywood Walk of Fame.
