She was born in Toronto, Canada. Addison has pointed out that she began her career very young, at fifteen, and feels she may have missed out on a “sparkly blue eyeshadow” period of youth when experimentation of personal style takes place, since she was being dressed and groomed by professional beauticians and stylists. She has light brown hair, green eyes, and is five feet ten inches tall. Her measurements are thirty-four inch bust, twenty-five inch waist, and thirty-four inch hips, and she wears a size four dress.
