There’s no denying this 25-year-old is Duff enough to lose some serious weight!

Hardly wanting to be outdone by fellow 2000s pop star Jessica Simpson — who’s also a new mom —Hilary Duff flaunted her post-baby body yesterday (November 20) as she hit up a gym in Toluca Lake, Calif.

The Lizzie McGuire star gave birth to son Luca in March and has since frequented the gym for workouts and Pilates classes, E! Online reports.... that is, when she’s not posting adorable shot after adorable shot of her little guy.

She’s looking great, but why she’s strangling her neck in a python-sized scarf is beyond us.
