It's unusual to spot a big celebrity not wearing make-up, but it does happen occasionally. Rihanna was out and about in New York City today showing off her fresh face. And she looked pretty good!

The pop star wore jeans and a white t-shirt with the slogan, "If I was riding a horse I'd wear flannel but I'm going to the disco so I wear Channel."

She smiled for photographers and also stopped to sign an autograph. We love a girl who doesn't mind going au naturale once in a while.

The singer just released her new music video "Where Have You Been" and has reportedly signed to star in "Fast & Furious 6."
