Traveling is stressful, even on A-list celebs like Cameron Diaz.

The star was on her way back to L.A. from Miami when she was snapped sans makeup, a fedora covering her golden locks. We can't blame her for not wanting a full face of product when on the go, dealing with stale, recirculated plane air.

She remains natural and lovely, even if she had a bit of a scowl on her face. Maybe she was tired or cranky or not happy about the text she as getting. Or maybe she didn't really feel like having a camera in her face as she deplaned!
