Singer Eydie Gorme, who enjoyed decades-long success as half of the duo Steve & Eydie and as a solo artist in her own right, has died. She was 84.

She is best known in the English-speaking world for her 1963 Grammy-nominated "Blame it on the Bossa Nova." In the Spanish-speaking market, Gorme's major hit was 1964's "Amor."

Gorme died Saturday in Las Vegas after a brief illness, her publicist said - without disclosing what had ailed her.
