From Meryl Streep and Michelle Obama to Lady Gaga and Snooki, these celebrities actually went to their prom ... and wore that.
Considering how larger than life they are now, it's pretty amazing to see just how innocent, sweet and awkward they once were.
Or in the case of Jaden Smith wearing a dress, just awkward:
