Hilary Duff Picks Up Protein Powder

Hilary Duff works up a good sweat with her personal trainer in West Hollywood and then drives home on Thursday.

The Duffster, 20, was helped out to her car because she decided to stock up on a bulk supply of protein powder. While she was loading up, Hilary also squashed all rumors about a wedding in the immediate future to her hockey player boyfriend Mike Comrie.

Hilary was seen wearing what appeared to be an engagement ring last Friday night when the couple went to Il Sole restaurant for dinner.
