"She and greeted her fans from her balcony and had a catered dinner for a dozen of her closest friends," Day's publicist Charley Cullen Walters told ABC News today of yesterday's party. "[I know] they sang songs ... 'Happy Birthday' and 'Que Sera, Sera.'
"She has the same bubbly personality and her laugh is just a contagious as it always was," Walters added. "She loves talking about the leading men she worked with throughout the years. She has so many fond memories of her career in Hollywood."
Day, who's also an animal rights activist, asked fans that, in lieu of gifts, they donate to her organization to help furry creatures in need.
"Her biggest passion for all of her life has been the Doris Day Animal Foundation," Walters said. "The site received a huge uptick of donations, so she was very thrilled with the response."
Two years ago, on her 90th birthday, the "Calamity Jane" star commemorated the occasion by taking photographs with about 200 fans who gathered at her home in Carmel, California -- an event that, Walters said, hadn't occurred in over 20 years.
"She obviously hasn't returned to Hollywood in a very long time [but] I admire her graceful desire to stay out of the limelight," Walters added. "She's enjoying her privacy, for now.... She's doing really great."
The Doris Day Animal Foundation (ddaf.org) was founded in 1978 and is a national nonprofit charity.
