Christina María Aguilera (/ˌæɡɪˈlɛərə/, Spanish: [aɣiˈleɾa]; born December 18, 1980) is an American singer, songwriter, and television personality. Her accolades include five Grammy Awards, one Latin Grammy Award, and a star on the Hollywood Walk of Fame, while she was also named the "Voice of a Generation" and honored as a Disney Legend in 2012 and 2019 respectively. Aguilera is one of the most influential and best-selling music artists of all time selling over 75 million albums and singles worldwide. In 2008, Aguilera ranked at number 58 on Rolling Stone's list of 100 Greatest Singers of All Time and has been noted for inspiring young artists.
Before rising to fame, Aguilera appeared on Disney's The Mickey Mouse Club before signing a recording contract with RCA Records in 1998. She achieved worldwide success with her self-titled debut album, released in 1999, which debuted at number one in the US and spawned three US number-one singles: "Genie in a Bottle", "What a Girl Wants", and "Come On Over Baby (All I Want Is You)". Aguilera followed her debut album up with Mi Reflejo and My Kind of Christmas (2000), with the former becoming the best-selling Latin pop album of the year. Becoming recognized as a prominent contemporary teen pop figure, Aguilera sought to assume artistic control with her follow-up album, Stripped (2002). Its lead single, "Dirrty", showed a drastic change in Aguilera's image as she began to express her sexuality. The second single from the album, "Beautiful", received favorable response for its empowering lyrics and became an anthem for the LGBT community as well as peaking number two on Billboard Hot 100.
Aguilera reinvented her image once more with her second US number-one album, Back to Basics (2006), which drew inspiration from early 20th-century jazz, soul, and blues, and spawned the top-ten singles "Ain't No Other Man", "Hurt", and "Candyman". Following suit, her next three albums, Bionic (2010), Lotus (2012), and Liberation (2018), all experimented with various musical styles and reached the top ten in the US. Outside of solo material, Aguilera has topped the Billboard Hot 100 twice with "Lady Marmalade", and as a featured artist on "Moves like Jagger". With the latter, Aguilera became the fourth female artist in history to top the chart in three consecutive decades. She also earned chart-topping entries with other collaborations including "Feel This Moment", "Say Something", and "Nobody Wants to Be Lonely".
In addition to her music career, Aguilera also starred in the film Burlesque (2010) and contributed to the soundtrack of the same name. "Bound to You", which Aguilera co-penned for the soundtrack, was nominated for a Golden Globe Award for Best Original Song but lost to another song from the same soundtrack. Aguilera also had a voice-over role in The Emoji Movie (2017), and was a coach on the singing competition television series The Voice for six seasons from 2011 to 2016.
