Prom season is almost upon us. Which means boys are renting tuxes and limos, girls are trying on frothy dresses, and everyone is prepping for an after-party filled with alcohol and lost virginities.

We kid. (Sort of.)

But the best thing about prom is having some of your worst fashion decisions preserved for all time on film ... and even celebrities aren't immune to that little personal nightmare.

From fried hair to awful gowns and even a tiara or two, the stars on this list would probably love a do-over. Let their pain be your schadenfreude -- and remember, embarrassing prom portraits are forever, but at least your mistakes aren't fodder for the whole internet.
