Georgina "GiGi" Giovanni is a super model with the super power of super charisma.
It is impossible to hate her. In fact, everyone loves her. They want to impress her, they want to be notices by her, they want her to even look their way.
Nothing she does or that happens to her can ever make her unattractive. Falls in pit of mud? Still sexy as hell. Hit by a car? Still gorgeous (and in immense pain).
Her powers are active in an aura around her, as well as in the very appearance of her in photos, billboards, advertisements in magazines, etc. Her voice alone, however, would not activate the power.
She is not kind to those around her, but it doesn't matter, they'll still love her anyways.
She has an assistant named Prudence. Prudence would love her and do anything for her, even without the powers
