Nicole Richie angrily confronted a photographer in California last weekend.

The Simple Life star was shopping in Malibu when the photographer reportedly yelled: "Nicole, you look disgusting. Gain some f**king weight!"

Richie was allegedly moved to tears by the comments, and returned later to confront the man.

She told US Weekly: "You don't scream at people that are overweight, so what makes people think that they have the right to scream at me that I am underweight? It's upsetting and mean. I am not anorexic. At that moment, I was just sick of everyone constantly bothering me about how I look.

"I walked up to the photographer and told him, 'What if I really had anorexia? What if I had a disease? How would you feel about saying such horrible things? He probably just wanted to get a rise out of me, but I'm a human being and he hurt my feelings."
