Rachel Bilson is leaving little to the imagination in this clingy Express dress on the cover of October's Women's Health Magazine.

The 30-year-old actress tells the mag:

    “I’m not the kind to go to the gym. You should enjoy food and enjoy life. Healthiness stems from being happy.”

As for turning the big 3 - 0, she adds:

    "Everyone tells you that things are going to change, so I’m waiting for something to happen. Like I’m going to grow another boob! But it is a milestone. You’re coming into your own.”

Thanks for the visual, Rachel!
