Hilary Duff is always smiling when she is out with her adorable son Luca and you rarely see a bad picture taken by the paparazzi of this duo. In fact, it looks like Luca is quite comfortable in front of the cameras as he smiles for them on this outing with mom. What do we notice other than his super cute smile? Equally as cute are those NUNUNU Black Star Leggings! When you have style like that you always look good (even at 1).
