Not to be confused with Dee Dee, Donna's mother.
DeeDee is the mother of Byron, one of Rallo's former classmates at the Stoolbend Daycare Center and married Fern Stapleton's ex-husband.
In "BFFs", Rallo gets invited to a reunion of his daycare graduation. While there, Donna feels she hasn't pushed Rallo to advance himself as the other class mothers have and Donna has Rallo compete in a Quiz Bowl tournament to prove that he is just as smart as the other kids in his class.
DeeDee is voiced by Reagan Gomez.
