Hilary Duff is a Workout Warrior

Hilary Duff heads to the gym in Los Angeles on Thursday (May 7).

The 21-year-old singer/actress from Houston, Texas showed off her curves last night as she co-hosted the Herve Leger by Max Azria Celebrationin Los Angeles.

Now that her boyfriend, Mike Comrie is in his hockey off-season, he’ll be around more to support her. She said, “He plays hockey in Ottawa, so he’s in town for the summer…so he’s gotta show up for all my stuff now since I’m constantly going to visit him. He’s a good sport about all of it, and he’s great. I’m happy to have him back!”
