Sahara Adelyn as Lady Tremaine. Lady Tremaine is cold, cruel, and bitterly jealous of Cinderella's charm and beauty, she was grimly determined to forward the interests of her own two daughters.

She is highly intelligent, manipulative and being able to recognize small details and to use them skillfully to serve her interests. She really doesn't deserve to be considered a mother.
