Gorme, who also had a huge solo hit in 1963 with "Blame it on the Bossa Nova," died Saturday at Sunrise Hospital in Las Vegas following a brief, undisclosed illness, said her publicist, Howard Bragman.
Gorme was a successful band singer and nightclub entertainer when she was invited to join the cast of Steve Allen's local New York television show in 1953.
She sang solos and also did duets and comedy skits with Lawrence, a rising young singer who had joined the show a year earlier. When the program became NBC's "Tonight Show" in 1954, the young couple went with it.
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."
