On Wednesday Hilary Duff and her darling son Luca were spotted after a mommy and me class in the valley, and the former Disney star couldn't stop smiling when we snapped her picture.

Hilary and hubby Mike Comrie welcomed their first child together back in March, and since then she has spoken out about the challenges and joys of motherhood, particularly when it comes to losing the baby weight.

In last month's issue of Parents Magazine, Duff said she embraces her curves, adding, "There are some women who look the same right after [giving birth] -- I think they are freaks of nature! I don't know how that happens. I'm not one of those people. It takes your body nine months to get there -- really ten months. So I'm trying to be patient but I'm working hard. And I think now more than ever, I appreciate my body and what it's done for me."
