Susie Diamond is a fictional character who appears in the romantic musical comedy-drama film The Fabulous Baker Boys (1989). Portrayed by Michelle Pfeiffer, Susie is a former escort who becomes a professional lounge singer when she is hired to help revitalize the career of The Fabulous Baker Boys, a waning piano duo consisting of brothers Jack and Frank Baker. Susie's addition to the group benefits both the trio's career and her own, but she also inadvertently generates conflict between the two brothers as Frank strongly disapproves of Jack's romantic interest in Susie, ultimately jeopardizing both the brothers' relationship with each other and the trio's future as a musical act.
