Legendary Hollywood star Doris Day passed away peacefully yesterday at the age of 97, and tributes to the actress, singer and animal rights activist have been flooding social media over the past day.

They include everyone from Paul McCartney, who called her a "true star" in a statement on his website. "So sad to hear of Doris Day passing away," he wrote. "She was a true star in more ways than one. I had the privilege of hanging out with her on a few occasions. Visiting her in her Californian home was like going to an animal sanctuary where her many dogs were taken care of in splendid style. She had a heart of gold and was a very funny lady who I shared many laughs with. Her films like 'Calamity Jane', 'Move Over, Darling' and many others were all incredible and her acting and singing always hit the mark. I will miss her but will always remember her twinkling smile and infectious laugh as well as the many great songs and movies she gave us. God bless Doris.'"

His daughter Stella McCartney also paid tribute to Day on Instagram:

Other stars who marked Day's passing and her extraordinary life via social media included Goldie Hawn, Antonio Banderas, William Shatner, and more.
