Shania Twain, OC (/ʃəˈnaɪ.ə/; born Eilleen Regina Edwards; August 28, 1965) is a Canadian singer and songwriter. She has sold over 100 million records, making her the best-selling female artist in country music history and among the best-selling music artists of all time. Her success garnered her several honorific titles including the "Queen of Country Pop".
Raised in Timmins, Ontario, Twain pursued singing and songwriting from a young age before signing with Mercury Nashville Records in the early 1990s. Her self-titled debut studio album saw little commercial success upon release in 1993. After collaborating with producer and later husband Robert John "Mutt" Lange, Twain rose to fame with her second studio album, The Woman in Me (1995), which brought her widespread success; it sold 20 million copies worldwide, spawned widely successful singles such as "Any Man of Mine", and earned her a Grammy Award. Her third studio album, Come On Over (1997), became the best-selling studio album of all-time by a female act in any genre and the best-selling country album, selling nearly 40 million copies worldwide. Come On Over produced twelve 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 studio album, Up! (2002), was also certified Diamond in the United States.
In 2004, Twain retired from performing and began an indefinite hiatus from music, revealing years later that diagnoses with Lyme disease and dysphonia led to a severely weakened singing voice. She chronicled her vocal rehabilitation on the OWN miniseries Why Not? with Shania Twain in 2011 and released her first single in six years, "Today Is Your Day", as well as publishing her autobiography, From This Moment On. Twain returned to the concert stage the following year with an exclusive concert residency at The Colosseum at Caesars Palace, Shania: Still the One, which ran until 2014. In 2015, she launched the North American Rock This Country Tour, which was billed as her farewell tour. Twain released her fifth studio album and first in 15 years in 2017, Now, and embarked on the Shania Now Tour in 2018.
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. According to the RIAA 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.
