Nicole Richie's Wintery Workout

Nearly unrecognizable as she left all bundled up, Nicole Richie went to the gym in Sherman Oaks, California on Saturday (December 15).

The former reality star wore a black coat, knit hat, gray scarf, and workout tights as she headed back to her car.

Last week, the 33-year-old fashion designer and her rock star husband Joel Madden celebrated an important milestone.

The Good Charlotte frontman tweeted a photo of the pair with the caption, "Special dedication to my wife. We just spent a few days off the grid celebrating our second wedding anniversary."
