Coco Rocha found a novel way to raise dough Tuesday at the Coalition for the Homeless benefit Artwalk NY. Following an auction of works by Andy Warhol and others, the flame-haired stunner said she’d dance if the audience — including Richard Gere, Alec Baldwin and Shepard Fairey — donated more for an “Emergency Feeding Program.” The crowd coughed up $35,000 in 60 seconds. So Rocha threw off her Fendi heels and did an Irish jig on the spot, to end the night.
