Piper is Kelly's smarty-pants younger sister. She's the classic overachiever with her sights set super high, and boy, we mean high. With a schoolgirl crush on the oh-so-cute and much older upperclassmen, Piper's not your typical middle schooler. She uses her smarts to come up with sneaky tricks to get her way - and Piper always gets her way.
Piper is played by Tiffany Espensen. She has guest starred on Nickelodeon's True Jackson, VP, and has been featured in Disney's Hannah Montana and Phineas and Ferb, where she voices Ginger. Other projects include voicing Alex O'Hare in the animated comedy film, Hop.
