Synopsis
A shy, but childlike and imaginative teenage girl named Kelly Knapp is a huge daydreamer as she one day wants to be the world's famous pop music star, as she deals with shenanigans.

Main

 * Kelly Knapp (voiced by Ashley Johnson) - A childlike and carefree, but shy, cute, and compassionate teenage girl who loves to daydream about being a famous pop star. She also has many hobbies, including drawing, reading, hanging out with her best friend, and her most favorite of all, singing karaoke songs, while also carrying around her favorite stuffed cat, Frostie.

Supporting

 * Patrick "Pat" Knapp (voiced by Clancy Brown) - A snarky, yet very caring man who is Kelly's father, always annoyed and driven bonkers by Kelly's childish behavior, but despite that, he deeply cares for her and finds her as his angel.
 * Patricia Moore (voiced by Hilary Duff) - A caring, fashion-loving and sometimes shy teenage girl who appears to be childish too and is Kelly's best friend, often supporting Kelly being a pop singer one day and can show her aggressive side when she or Kelly get attacked. She is also huge into fashion, both those that aimed for kids and other normal fashion too.
 * Lauren Espraña (voiced by Grey DeLisle) - A snobbish and spoiled, but secretly childish and somewhat friendly teenage girl who usually picks on Kelly and Patricia, but at the same time, has Friendly Moments with them, serving as their friendly rival
 * Callie Bigway (voiced by TBD) - a sarcastic pop star who is Kelly's idol as she is slightly obsessed with her.
 * Mr. Bruce Irvine (voiced by TBD) - an easily bored man who is a teacher of Kelly's school, often getting bored at his job.
 * Mr. Hanks (voiced by TBD) - a calm and gentle man who is the host of Mr. Hanks' Wonderful City, being one of Kelly, Patricia and (secretly) Lauren's favorite show. He is as kind in real life as he is in his show.
 * Mary (voiced by Tara Strong) - a giddy and happy pink monster muppet wearing a bow who is Mr. Hanks' best friend.
 * Icy (voiced by Nika Futterman) - A giddy and intelligent baby seal who loves to entertain children on his show Counting with Icy, as he is just as kind in real life to his fans as he is on his show

Antagonists

 * Brock Hunter (voiced by Jeff Bennett) - a dim-witted jock who uses Kelly and Patricia’s childish behavior to his advantage, always finding new ways to torment and harass them.
 * Brittney Knapp (voiced by TBD) - Kelly’s much younger sister who thinks her sister watching preschool shows is dumb and calls them “baby shows”, even going as far as bullying her for it - which is ironic considering her age.
 * Brian Mellow (voiced by TBD) - a rude and easily annoyed store manager who dislikes Kelly due to her childish behavior, and will do anything to try and send her out, albeit with funny fails.
