Britney Jean Spears (born December 2, 1981) is an American singer and actress. Born in McComb, Mississippi, and raised in Kentwood, Louisiana, she performed acting roles in stage productions and television shows as a child before signing with Jive Records in 1997. Spears's first and second studio albums, ...Baby One More Time (1999) and Oops!... I Did It Again (2000), became international successes, with the former becoming the best-selling album by a teenage solo artist. Title tracks "...Baby One More Time" and "Oops!... I Did It Again" broke international sales records. In 2001, Spears released her self-titled third studio album, Britney, and played the starring role in the film Crossroads (2002). She assumed creative control of her fourth studio album, In the Zone (2003), which yielded the worldwide success of the "Toxic" single.

In 2007, Spears's much-publicized personal issues sent her career into hiatus. Her fifth studio album, Blackout, was released later that year, and spawned hits such as "Gimme More" and "Piece of Me". Her erratic behavior and hospitalizations continued through the following year, at which point she was placed under a still on-going conservatorship. Spears's sixth studio album, Circus (2008), included global chart-topping lead single "Womanizer". Its supporting tour The Circus Starring Britney Spears was one of the highest-grossing global concert tours in 2009. Later that October, "3" became Spears's third single to reach number one on the Billboard Hot 100. Her seventh studio album, Femme Fatale (2011), became her first to yield three top-ten singles in the United States: "Hold It Against Me", "Till the World Ends" and "I Wanna Go". She also served as a judge during the second season of the American version of The X Factor. Spears's eponymous eighth studio album Britney Jean was released in 2013; it spawned the top 15 hit "Work Bitch", however it became the lowest-selling record of her career. Later that year, Spears began the two-year residency show Britney: Piece of Me at The AXIS at Planet Hollywood Resort & Casino in Las Vegas.
