Kelly has long brown hair which is usually let loose. She has olive skin, rosy cheeks, and dark brown eyes. Her wardrobe usually consists of casual flowy tops, button-ups and solid colour t-shirts. She usually wears t-shirts or knee-length shorts and is sometimes seen in jeans on a rare occasion. Her hair is pinned back on one side in almost every episode, either by a french braid, a simple twist. She usually wears 2 or 3 colored bobby pins. On a rare occasion, she wears a ponytail. Kelly's hair was curled in the Season 1 pilot and was a light chestnut color but in more recent episodes is a long, straight dark brown. She never paints her nails as they are always kept short and clean.
Kelly is always willing to help out others, especially her friends and her grandmother. She is strong-willed and doesn't let anything get to her head. She can be pretty naive at times and doesn't believe in things that she knows aren't true. She also is very sensitive and is very gullible, especially in season 1 when she thinks that Hannah betrays her and instead gets tricked into working with Mama P. She can be a little selfish like when she almost sacrificed her friends and family to get what she wanted. Kelly can be bossy but has great ideas. She is passionate in what she cares about. She cooks many recipes and is addicted to her cookbook. One of Kelly's main traits is to always do things on her own and not wait for other people. She soon realizes this trait in Just Add Gumdrops.
- Two of her fears are snakes and losing the magic cookbook.
- She has known Darbie and Hannah since kindergarten.
