Mrs. Stevens is Bebe Stevens' mother. She is a very stereotypical, large-chested dumb blonde who relies on her looks to get her through most of her life, of which characteristic she has passed on to her daughter, but Bebe kept resisting when her breasts started to grow early in the episode "Bebe's Boobs Destroy Society". Mrs. Stevens is married to Mr. Stevens.
Mrs. Stevens wears a pink blouse over a white collared shirt. She wears purple trousers and a lot of makeup, which consists of purple eyeshadow, and red lipstick. She also wears black shoes and earrings. She has short blond hair which is combed to one side.
