''Doris' wishes were that she have no funeral or memorial service and no grave marker. Friends and fans wishing to remember Doris Day, are encouraged to visit www.dorisdayanimalfoundation.org.''

The foundation broke the news of Doris' death, and revealed she had been in good health until recently falling ill.

They said in a statement: '' Day had been in excellent physical health for her age, until recently contracting a serious case of pneumonia , resulting in her death. She was surrounded by a few close friends as she passed.''

Meanwhile, a host of stars have taken to their social media accounts to pay tribute to the singer-and-actress.

William posted: ''Condolences to the family of Doris Day. She was the World's Sweetheart and beloved by all. Que Será, Será! (sic)''

And George tweeted: ''For those of us in my generation, Doris Day was synonymous with Hollywood icon. She would no doubt remind us, upon this day of her passing, ''Que sera sera,'' but we will miss her dearly anyway. Rest now in our hearts forever, Ms. Day.(sic)''
