Shania Twain, (born Eilleen Regina Edwards; August 28, 1965) is a Canadian singer and songwriter. Twain has sold over 85 million records, making her one of the world's best-selling artists of all time. She is also the best selling female artist in the history of country music, which garnered her honorific titles including the "Queen of Country Pop".

Twain's second studio album, 1995's The Woman in Me, brought her widespread fame. It sold 20 million copies worldwide, spawning hits such as "Any Man Of Mine" and earning her a Grammy Award. Twain's third album, Come On Over, became the best-selling studio album of all time by a female act in any genre and the best-selling country album of all time, selling around 40 million copies worldwide. Come On Over produced several singles, including "You're Still the One", "From This Moment On" and "Man! I Feel Like a Woman!", and earned Twain four Grammy Awards. Her fourth and latest studio album, Up!, was released in 2002 and, like her previous two albums, was also certified Diamond in the U.S., spawning hits like "I'm Gonna Getcha Good!" and "Forever and for Always".

Twain has received five Grammy Awards, 27 BMI Songwriter awards, stars on Canada's Walk of Fame and the Hollywood Walk of Fame, and an induction into the Canadian Music Hall of Fame. She is the only female artist in history to have three consecutive albums certified Diamond by the RIAA. Altogether, Twain is ranked as the 10th best-selling artist of the Nielsen SoundScan era.

In 2004, Twain retired from performing and retreated to her home in Switzerland. In her 2011 autobiography, she cited a weakening singing voice as the reason for not performing publicly.When both her singing and speaking were affected, Twain consulted the Vanderbilt Dayani Center in Nashville. Specialists discovered lesions on her vocal cords and diagnosed her with dysphonia, all treatable with careful rehabilitation. In 2012, Twain returned to the concert stage in her critically acclaimed show Still the One, exclusively at The Colosseum at Caesars Palace.
