Doris Day, who used her girl-next-door good looks to charm American audiences during a decades-long acting and singing career died on 13th May. She was 97. Best known for her wistful song "Que Sera, Sera," the versatile singer passed way surrounded by close friends at her home near Carmel Valley, California, the Doris Day Animal Foundation stated.

According to the foundation She "had been in excellent physical health for her age until recently contracting a serious case of pneumonia,” Day, who turned 97 on April 3, broke into show business as a singer, and recorded a hit, "Sentimental Journey," with bandleader Les Brown in 1945. That and “Que Sera, Sera” — which Day performed in Alfred Hitchcock's 1956 thriller "The Man Who Knew Too Much" — were some her biggest chart-toppers.

The multitalented Day would jump off the turntable and on to the big screen, with credits in 39 movies. Her best-known screen works include "Calamity Jane" in 1953, "Love Me or Leave Me" in 1955, "The Man Who Knew Too Much" in 1956, "Pillow Talk" in 1959, "Lover Come Back" in 1960 and "Move Over, Darling" in 1963.

She was married four times, which conflicted with her squeaky-clean public and big-screen persona. In her 1976 book, "Doris Day: Her Own Story," the actress said her real life was much more complicated.

In her post-entertainment career, Day directed most of her energy into animal rights, through her Doris Day Animal Foundation and the Doris Day Animal League. The legendary entertainer's "wishes were that she has no funeral or memorial service and no grave marker," according to her foundation's statement.
