Dion is a Canadian singer, songwriter, businesswoman and occasional actress. Born into a large family from Charlemagne, Quebec, Dion emerged as a teen star in the French-speaking world after her manager and future husband René Angélil mortgaged his home to finance her first record. In 1990, she released the English-language album Unison, establishing herself as a viable pop artist in North America and other English-speaking areas of the world.

Dion first gained international recognition in the 1980s by winning both the 1982 Yamaha World Popular Song Festival and the 1988 Eurovision Song Contest where she represented Switzerland. Following a series of French albums in the early 1980s, she signed on to CBS Records Canada in 1986. During the 1990s, with the help of Angélil, she achieved worldwide fame after signing with Epic Records and releasing several English albums along with additional French albums, becoming one of the most successful artists in pop music history. However, in 1999 at the height of her success, Dion announced a hiatus from entertainment in order to start a family and spend time with her husband, who had been diagnosed with cancer. She returned to the top of pop music in 2002 and signed a three-year (later extended to almost five years) contract to perform nightly in a five-star theatrical show at the Colosseum at Caesars Palace, Paradise, Nevada.

Dion's music has been influenced by genres ranging from rock and R&B to gospel and classical. Her recordings are mainly in French and English, although she also sings in Spanish, Italian, German, Latin, Japanese and Mandarin Chinese. While her releases have often received mixed critical reception, she is renowned for her technically skilled and powerful vocals. Dion has won five Grammy Awards, including Album of the Year for Falling Into You and Record of the Year for "My Heart Will Go On". She is the second best-selling female artist in the US during the Nielsen SoundScan era, with her albums Falling Into You and Let's Talk About Love both certified Diamond in the US, In addition, her 1995 album D'eux, is the best-selling French-language album of all time. In 2004, after surpassing 175 million in album sales worldwide, she was presented with the Chopard Diamond Award at the World Music Awards for becoming the best-selling female artist of all time. Dion remains the best-selling Canadian artist in history and one of the best-selling artists of all time with album sales of more than 200 million copies worldwide.
