Mirrors are usually Adriana Lima's best friend, but this afternoon in New York City ... they were her mortal enemy.
Lima was shooting a Maybelline commercial in SoHo Tuesday as she walked around her trailer to get to the door ... all while a gaggle of photogs snapped away.
As Lima turned the corner, she ran SMACK into the bus mirror and hit the ground like a ton of bricks. Or, considering Lima is a supermodel, more like 90 pounds of bricks.
Don't worry, we're sure she'll have no problem finding someone to kiss her boo-boo.
