Hilary Duff Santa Monica

Oh, what we wouldn't give to raid Hilary Duff's closet ... and as if we weren't already a huge fan of the Duffster, we love that she's always in a good mood when she sees us!

On Friday X17 photographers snapped the former Disney star out and about in Santa Monica, and even though she wasn't wearing anything colorful, she was able to brighten our day with her megawatt smile.

Duff was busy this week with Halloween festivities, and in between trick or treating with her one-and-a-half-year-old and going to some more adult costume parties, she dressed as mouse and later as a cat. Meanwhile, hubby Mike Comrie and their darling son Luca teamed up and dressed as firemen:
