Movie legend Doris Day stunned fans at an event to mark her 90th birthday last week (04Apr14) when she showed up to join in the festivities.

The Pillow Talk star, who hasn't made a public appearance in over two decades, wasn't expected to attend the annual Doris Day Animal Foundation benefit, and her surprise entrance left many guests in tears.

Held a day after her birthday at the Cypress Inn in her adopted Carmel, California on 4 April (14), the party was thrown to raise funds and awareness for the actress' animal charity - but she never usually shows up.

Thrilled Day tells People.com, "I couldn't believe it. People kept coming up to me all night, kissing and hugging me. It's all so exciting and sweet. I'll never ever forget it."
