Mary-Kate was looking a little bit sass-factor leaving the set of Weeds [1] on Friday. Look at her all adult like taking on her first real acting job -- and she looks so happy with her co-workers [1]. I feel like a proud mother. Yeah, that's a little awkward. But seriously though, when was the last time we saw MK in flats? It's probably been years. And have I mentioned how excited I am for the return of Weeds? Yeah, just a few times [1].
