Hilary, 26, added a pair of sunglasses and a simple blue jumper to complete her off-duty look.
The actress had just dropped her super cute son Luca off at baby class in Los Angeles, where all the most fabulous tots gather to hang out and learn baby stuff, obvs.
Hilary has scaled back her work commitments, taking time off to focus on her son ever since she gave birth in March 2012, but now she's planning a comeback.
She's been working on a new album, and told Parade: "Work makes me happy, and I know I need it in my life, but it's just going to some time to find exactly what I want to do and how much time I feel I can spend away. It's all trial and error."
It's not all work for Hilary though, as the fun-loving star always has time for a little entertainment.
Earlier this week she posted a picture of herself on Twitter wearing a comedy moustache.
We'd like to know how Hilary still manages to look like a major babe while sporting a 'tache!
