"My Heart Belongs to Daddy" is a song written by Cole Porter, for the 1938 musical Leave It to Me! which premiered on November 9, 1938. It was originally performed by Mary Martin, who played Dolly Winslow, the young "protégée" of a rich newspaper publisher. In the original context, Dolly is stranded at a Siberian railway station, wearing only a fur coat, and performs a striptease while singing the song. Surrounded by eager Siberian men, she says that since she has met "daddy", she will flirt with other men, but won't "follow through". "Daddy" is her sugar daddy, a newspaper magnate introduced with the words, "I've come to care, for such a sweet millionaire". Later versions Martin sang it again in the 1940 movie Love Thy Neighbor. Again she wears a fur coat, but the setting is a show within a show and the act is more conventional as she wears an evening gown beneath the fur. The words to the introduction are altered, the innuendoes being toned down. Her best-known movie performance is in the 1946 Cole Porter biopic Night and Day in which she plays herself. The film recreates Martin's audition then segues into her performance in the original Siberian context. She again performs the striptease, discarding her muff and then the fur coat, while mustachioed Siberian men follow her every move, eventually fainting when she removes her coat to reveal a skimpy figure-hugging costume beneath. In Britain, the song was a hit for Pat Kirkwood who performed it in the 1938 revue Black Velvet. This led to her being dubbed "Britain's first wartime star". The song was thereafter associated with her. Marilyn Monroe sings the song in the film Let's Make Love (1960). The introduction is completely changed. She introduces herself as "Lolita", who is not allowed to "play with boys". A verse is added in which she invites a boy "to cook up a fine enchilada". The lines do not conform to the rhyme scheme of the rest of the song, but have been used by many other performers since. Anna Nicole Smith recorded a copy of the Monroe version in 1997, it was released in CD-single and 12 maxi with two versions. Lyrical and musical features Rhyming with "daddy" is difficult but Porter characteristically managed it well. One clever rhyme is Finnan haddie is smoked fish, and this is one of many innuendoes which appear
