Linda, Be Good (1947)

Linda Prentiss joins a burlesque troupe to get information for a novel she is writing without her husband, Roger Prentiss, knowing about it. Not knowing who he is, she meets her husband's boss, Sam Thompson, while on a night-clubbing tour with the show's burlesque queen Margie LaVitte. Later, the boss takes a client and Roger to the burlesque show, and Roger is stunned to see his wife as one of the stars.
