Christina María Aguilera is an American singer, songwriter, actress, and television personality. Recognized as an influential figure in music and having received widespread public interest, she is noted for her four-octave vocal range extending into the whistle register, artistic reinventions, and incorporating controversial themes into her music. Referred to as the "Voice of a Generation", she was also named a Disney Legend, in recognition of her contributions to the Walt Disney Company.
After appearing on The All New Mickey Mouse Club (1993–1994), Aguilera recorded the theme song, "Reflection", for the animated film Mulan (1998) and signed a record deal with RCA Records. She rose to fame in 1999 with her self-titled debut album, which topped the US Billboard 200 and garnered three US Billboard Hot 100 number-one singles: "Genie in a Bottle", "What a Girl Wants" and "Come on Over Baby (All I Want Is You)". Seeking a departure from her teen idol image, Aguilera took on a more provocative image on Stripped (2002), one of the best-selling albums of the 21st century.
