Christina María Aguilera (born December 18, 1981) is a four time Grammy Award winning American pop singer and songwriter. She was signed to RCA Records after recording "Reflection" for the film Mulan, and her bubblegum pop-oriented debut album Christina Aguilera (1999) was a critical and commercial success: it produced four hit singles, including "Genie in a Bottle", and helped Aguilera win a Grammy Award.

A Latin pop album and a Christmas LP released during this period also sold strongly. In 2001, she participated in collaboration projects for Ricky Martin's Sound Loaded album and the Moulin Rouge! soundtrack.

Aguilera took creative control over her second studio album Stripped (2002), which produced the hip-hop-influenced "Dirrty" and the award-winning "Beautiful". It received mixed reviews, and Aguilera's increasingly sexual image during its promotion became the subject of much criticism and controversy. She contributed to several other artists' songs in 2004 and 2005 and married record executive Jordan Bratman.

Her third studio album Back to Basics (2006), which was preceded by the hit single "Ain't No Other Man", included elements of soul, jazz and blues music and was released to average sales and positive critical reception. Aguilera's works have earned her five Grammy Awards amongst sixteen nominations, 2 ALMA Awards, and over 30 million album sales worldwide
