Shania Twain, OC (born Eilleen Regina Edwards; August 28, 1965) is a Canadian country music singer-songwriter. Referred to as "The Queen of Country Pop," She is also the best selling female artist in the history of country music.Twain's 1995 album, The Woman in Me, brought her fame and sold 20 million copies worldwide, and her 1997 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. Her fourth and last studio album to date, Up!, was released in November 2002. Twain is often recognized for reaching beyond all feasible music boundaries with only three studio albums. She is the first (and currently only) female artist in history to have 3 consecutive albums certified Diamond by the RIAA. With over 40 million copies sold worldwide, Come On Over is the best-selling album by a female artist and the top-selling country album of all time. Altogether, Twain is ranked as the 10th best-selling artist of the Nielsen SoundScan era.
In 2004, Twain retired from performing and quietly retreated to her home in Switzerland. 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.
