Olivia Wilde Works Up A Wild Sweat At The Gym

She must have hit the treadmill hard!

Olivia Wilde was caught on camera in El Lay on Thursday afternoon looking a little damp after what must have been a demanding workout at the gym.

The Cowboys & Aliens actress casually walked past photographers on the way to her car with a smile on her face and sweat-drenched clothes on her body.

You know you got a good workout in when people can see through your shirt in a photograph! Ha!
