Studio City Nicole Richie gym workout tights hoodie

Props to Nic! Lionel Richie's just-married daughter continues working on her fitness at the gym in Studio City despite the fact that she already tied the knot with longtime love Joel Madden. And she does it without any makeup on! Au naturel is the best way to go when you're as lovely as Nicole!

But where's her gym buddy Khloe Kardashian?
