Stuart is best known for her role as Donna Love Hudson on Another World, which she played from January 1983 to November 1986 and again from February 1989 to the show's final episode in June 1999.
At first a supporting character, Donna was slowly made a lead as she became involved in a triangle with ex-husband Carl Hutchins and flashy novelist Felicia Gallant.
As Stuart became more popular, a major romance was created for her with Michael Hudson (Kale Browne) who was Victoria and Marley's father.
When Stuart left the show in 1986, the role of Donna was recast with Philece Sampler, previously of the serial Days of Our Lives in the early 1980s.
Immediately following this, Stuart began the role of Mary Smythe (Greenlee's neglectful and self-centered mother) on All My Children where she played opposite former Another World castmate Mark Pinter.
Intended to be written in for only a short length of time, the character became integral in a plotline in which Mary revealed that Jackson Montgomery was Greenlee's natural father, making her the latest in the long line of rivals to that show's reigning queen, Erica Kane.
