While 13 Going on 30 isn't exactly a teen movie, it has the same kind of warmhearted spirit, throwback vibes, and sweet romance that Clueless is known for. Unpopular teen Jenna makes a wish on her 13th birthday to be "thirty and flirty and thriving," then suddenly wakes up to find that her wish has come true. After discovering that her future self is successful but also selfish and shallow, Jenna tries to make things right. With the help of her middle school BFF Matt, with whom her adult self had long ago lost touch, Jenna just might be able to transform her life into something that her teenage self can be proud of, too.
