Kidman appeared on the red carpet Thursday night celebrating Francisco Costa's 10th anniversary as the women's creative director of the Calvin Klein Collection.
Earlier, the 46-year-old actress was outside a hotel when she was hit by a bicyclist. She was knocked to the ground, but in an interview with The Associated Press at the Calvin Klein event, she said she was OK.
Kidman added: "I'm up, I'm walking around, but I was shaken."
The New York Police Department says a 19-year-old bicyclist was issued three summonses for riding a bike on the sidewalk, riding a bike with no helmet and reckless endangerment.
