Adriana Lima smacks head on bus mirror

For a person who makes millions by looking graceful while walking, Adriana Lima sure is clumsy.

Paparazzi video has shown the Brazilian Victoria's Secret model strutting beside a bus on a New York street, dressed in jeans and a fur vest.

But as Lima rounds a corner she smacks her head on the bus's side mirror, knocking her off her feet.

What makes the accident more ridiculous is that Lima appears to duck to avoid the mirror, but raises her head too early, resulting in the forehead injury.

Fortunately Lima was able to climb aboard the bus immediately, preventing the paparazzi from capturing her embarrassment at the blunder.

It's been a week of ups and downs for Lima, announcing her separation from her NBA star husband Marko Jaric before wowing the red carpet at the Met Gala on Monday night.
