Men in Her Diary (1945)

Singer/Dancer Peggy Ryan neither sings nor dances in this comedy in which she plays a secretary, whose life has no romance because she devotes all of her time to her attractive older sister. But she does keep a diary that contains some fact and many fictional entries. One such is read by the wife of her boss who promptly sues for a divorce. Virginia Grey stars in a musical produced by Hall and sings (possibly dubbed) "Makin' a Million" and "Keep Your Chin Up." No spoiler to add that Ryan gets a boyfriend and Hall and Allbritton are reunited before this one runs it course.
