Cher

Cher is not only an iconic singer; she is also an accomplished actress. This has enabled her to become one of the small group of artists to take home a Grammy, Oscar, and Emmy award. She began her music career as a teenage backup singer in Phil Spector's legendary Wall of Sound, was half of the highly successful duo Sonny and Cher with her husband Sonny Bono, and then fully eclipsed that success as a solo artist. Her first farewell concert tour took a phenomenal three years to complete largely due to the demand for tickets from her fans. She is the first artist to earn a #1 hit on at least one Billboard chart in every decade from the 1960s to the 2010s. Cher is estimated to have sold 200 million records worldwide.
