Marilyn Monroe was a model-turned-actress in the early to mid 20th century. In 1952, she met the Doctor at a Hollywood party, and he "accidentally" accepted a marriage proposal from her. He tried to avoid it, but ended up leaving the party with her to get married. Marilyn gained the Doctor's phone number during this time, and later attempted to call him, though he denied the legitimacy of the chapel. (DW: A Christmas Carol)
