Hilary's Evolution!
From Lizzie McGuire to wife!
It’s been awhile since we’ve seen this expectant mommy!

Hilary Duff was spotted outside a piloxing (pilates and kickboxing) studio in Toluca Lake on Thursday, and looked cute and casual in a gray t-shirt.

 While it’s not completely visible, you can get a quick peak at her growing bump!

The 24-year-old actress is currently expecting her first child with hockey playing husband of one year Mike Comrie.
