Christina María Aguilera is an American singer, songwriter, actress, and television personality. Referred to as the "Voice of a Generation", she is known for her four-octave vocal range, use of melismatic singing, and ability to sustain high notes. For her work, which incorporates themes of feminism, sexuality, and domestic violence, she has generated both critical praise and controversy, and is considered a pop culture icon as well as a triple threat entertainer for her work outside of music. Aguilera rose to prominence after self-titled debut album was released through RCA Records in 1999, which produced the US Billboard Hot 100 number-one singles "Genie in a Bottle", "What a Girl Wants", and "Come On Over Baby". The album's teen pop is credited with influencing the revival of teen pop during the late 1990s and early 2000s.
