Fashion victim! Lady Gaga takes a bad fall while trying to walk in sky-high platform heels

These boots weren't made for walking.

Lady Gaga fell flat on her face yesterday when she tried to sashay through London's Heathrow airport in a pair of thigh-high, black-leather boots with massive platform heels.

Instead of making a statement, the boundry-pushing performer became a fashion victim as she tumbled to the floor.
