Nicole Richie so Skinny

Yes. This is Nicole Richie heading to the Marc Jacobs store.

The celebutante headed back for another round of shopping at the Melrose Ave. shop, where she was also seen the day before, having her photo taken with Santa.

Richie was again photographed on Santa's lap before purchasing a scarf -- and chewing the tag off of it. At least she's eating something.
