Hilary Duff stayed true to her stylish self in her striped cardigan as she headed back to her car after a trip to the gym in LA yesterday. Hil has been staying low-key ever since those engagment rumors back in August, but judging from that big smile, all is still well with the starlet. It's only a few more weeks until her boyfriend Mike Comrie will be back to playing hockey, so hopefully she'll get some romantic time in before she's back to cheering him on from the stands.
