Hollywood legend Doris Day, whose films made her one of the biggest stars of all time, has died aged 97.
The singer turned actress starred in films such as Calamity Jane and Pillow Talk and had a hit in 1956 with Que Sera, Sera (Whatever Will Be, Will Be).
Her screen partnership with Rock Hudson is one of the best-known in the history of romantic movies.
In a statement, the Doris Day Animal Foundation said she died on Monday at her home in Carmel Valley, California.
Born Doris Mary Ann Von Kappelhoff in April 1922, Day originally wanted to be a dancer but had to abandon her dream after breaking her right leg in a car accident.
Instead she began her singing career at the age of 15. Her first hit, Sentimental Journey, would become a signature tune.
Her films, which included Alfred Hitchcock’s The Man Who Knew Too Much and That Touch of Mink, made her known around the world.
But she never won an Oscar and was nominated only once, in 1960, for Pillow Talk, the first of her three romantic comedies with Hudson.
Honours she did receive included the Presidential Medal of Freedom in 2004 and a lifetime achievement Grammy in 2008.
Her last release, the compilation album My Heart, went to number one in the UK in 2011.
Day’s wholesome, girl-next-door image was a popular part of her myth that sometimes invited ridicule.
“I’ve been around so long, I knew Doris Day before she was a virgin,” the musician Oscar Levant once remarked.
Day herself said her “Miss Chastity Belt” image was “more make-believe than any film part [she] ever played.”
Her life was certainly not as sunny. She married four times, was divorced three times and was widowed once.
She also suffered a mental breakdown and had severe financial trouble after one husband squandered her money.
In the 1970s, she turned away from performing to focus her energies on her animal foundation.
According to the organisation, she wished to have no funeral, memorial service or grave marker.
Dick Van Dyke, another Hollywood legend from the same era although he never worked with Day, said she had an “energy about her”.
“She wasn’t trying to act. It was just who Doris Day was, I think, a great energy and exhilaration, and she seemed to love life, at least that’s the impression you got,” he told BBC Radio 4’s PM programme. “It was a great era.”
Star Trek actor William Shatner remembered Day on Twitter as “the World’s Sweetheart,” saying she was “beloved by all”.
Fellow Star Trek cast member George Takei said she was “synonymous with Hollywood icon”, while Spanish actor Antonio Banderas wrote: “Thank you for your talent.”
Novelist Paulo Coelho marked her passing by quoting lyrics from Secret Love, one of her numbers in Calamity Jane.
“We’ve lost another great Hollywood talent,” tweeted Family Guy creator Seth MacFarlane, while actor Luke Evans said he had “always loved” her voice and “beautiful” songs.
Former Beatles member Paul McCartney paid tribute to Day on his website, describing her as “very funny lady who I shared many laughs with”, adding: “I will miss her but will always remember her twinkling smile and infectious laugh”.
And his daughter, fashion designer Stella McCartney, shared a photo of her and Day alongside words which read: “The one, the only, the woman who inspired so much of what I do.”
