Jenny is a teenage girl who attends Tribeca Prep with the Russo wizards and their friends. She's played by Gilland Jones, and is notorious for being extremely obnoxious and giddy, which drives her ex-boyfriend TJ to turn her into a forty year old woman(played by Heidi Swedberg) who teaches art at the school. Alex reverses this but shortly realizes the mistake she made when there is no longer a teacher to teach her favorite class. She enjoys texting and eating strawberry lip gloss like it's candy, and doesn't mind receiving credit for things she didn't do.
