Nicole Kidman is pressing charges against a paparazzo who crashed into her on a bicycle, knocking her to the ground.
Nicole had just left the Calvin Klein show for New York's Fashion Week and was returning to the Carlyle Hotel. As she walked toward the entrance, a freelance photog named Carl Wu was roaring toward her on his bike.
Witnesses tell TMZ ... as Wu got dangerously close to Nicole, he appeared to hit his brakes, but it didn't do the trick. He slammed into her and she went crashing to the ground.
A photog who was there tells TMZ ... Nicole was furious and said she wanted to press charges against Wu. Nicole called the cops, and they're on the way right now.
Wu is a notorious photog who has had run-ins with other celebs, including Lada Gaga. There's actually a Tumblr account called, "F**k You Carl Wu."
As for Nicole ... no word on whether she's injured -- though paramedics were on scene ... just in case.
