Scarlet! Supermodel Skips the Knickers, Then Takes an Ass-Flashing Fall on Stage

Check out Heidi’s hide!

Stunning Project Runway host Heidi Klum attended the Toys 'R' Us Children's Gala in NYC in a floor-length sparkly gown that was a complete wow on the red carpet.

Unfortunately, the sky-high split meant that Klum opted to go commando, and naturally, that would be the one time that a supermodel goes and takes a tumble.

Klum fell over while on the stage with her pal Martin Short, and flashed her pert posterior to the assembled crowd, taking short down with her.

In true Klum style though, she was quick to make a joke about it, even posting the offending snaps to her Twitter account with a ‘No Comment’ message.

Well played Heidi. And if it’s any consolation, if we had an ass like yours we'd flash it just about anywhere…
