Ronnie Spector, the cat-eyed, bee-hived rock ‘n’ roll siren who sang such 1960s hits as “Be My Baby,” “Baby I Love You” and “Walking in the Rain” as the leader of the girl group the Ronettes, has died. She was 78. Spector died Wednesday after a brief battle with cancer, her family said. “Ronnie lived her life with a twinkle in her eye, a spunky attitude, a wicked sense of humor and a smile on her face. She was filled with love and gratitude,” a statement said. No other details were revealed.
