Julia Roberts Doesn't Wear Deodorant

What's that smell?! It may be Julia Roberts, who admits to not wearing deodorant.  She appeared on Oprah yesterday for the Earth Day episode, and talked about changes people can make in their every day lives to save the environment.

One of them is not wearing deodorant, which seemed odd. She did admit to "freshening up" mid day, but didn't give us any pointers.  Even Oprah was a bit taken aback. Would you give up deodorant to go green?
