They married in Las Vegas in 1957 and later performed for audiences there. Lawrence, the couple's son David and other loved ones were by her side when she died, Bragman said.
"Eydie has been my partner on stage and in life for more than 55 years," Lawrence said in a statement. "I fell in love with her the moment I saw her and even more the first time I heard her sing. While my personal loss is unimaginable, the world has lost one of the greatest pop vocalists of all time."
Although usually recognized for her musical partnership with Lawrence, Gorme broke through on her own with the Grammy-nominated "Blame it on the Bossa Nova." The bouncy tune about a dance craze of the time was written by the Tin Pan Alley songwriting team of Barry Mann and Cynthia Weil.
Actually it was more the Brill Building than Tin Pan Alley (which refers to the earlier 20th century in popular music).
