dress Hilary Duff pregnant dog striped dress boots sunglasses

Aw, it's her four-legged child!

Hilary Duff was spotted taking her pooch to the vet in the valley on Tuesday, and we're not sure if she saw pictures of herself from the other day, but the pregnant starlet ditched her sweatpants and went with a way sexier boots and dress combo.

We can't really see her bump, but we must admit, pregnancy definitely suits her! Who knew Lizzie McGuire would make such a hot mama?
