File under the category: The Show Must Go On. As a fashion icon collapsed and died at a show during New York fashion week, the runway models didn't miss a step as they pranced past her.
TMZ obtained footage from the Joanna Mastroianni Autumn/Winter 2012 show on Feb. 15 ... which shows three men rushing to Zelda Kaplan's aid after she lapsed into unconsciousness in her front row seat.
Some of the lights were turned on ... and people can be seen crossing over the runway to help out ... but the ultra-focused models continue their walks without ever breaking stride.
Eventually, Zelda was carried out by 4 people and taken to a nearby hospital, where she was pronounced dead a short time later.
FYI -- models are usually given strict orders to ignore EVERYTHING that happens in the crowd when they're on the runway. Clearly, these models took their instructions to heart.
