Famous friends of Doris Day send their greetings to the singer and actress on her 90th birthday.

Doris Day, one of the most versatile and endearing talents in all of show business and one of the most devoted and inspiring advocates for the care of animals, turns 90 today, April 3.

This celebrity-filled video of birthday greetings reflects just a fraction of the love people everywhere have for this extraordinary artist, who cast a spell in many a movie and in many a song, a spell that will never wear off. (It is ridiculous that she has not received an honorary Academy Award, given the indelible contributions she made to the movie industry. But that's another story).

Instead of cards or gifts, she asks her fans to mark the occasion by making a donation to the Doris Day Animal Foundation.
