Jennifer Aniston is known for her healthy lifestyle, but she admitted she once ate a Big Mac and things didn't end very well.

"I'll never forget when Justin [Theroux] and I were on a road trip and we were so hungry," she told her stylist, when the two interviewed each other for NY Mag. "The only thing around was McDonald's. I think I ordered a Big Mac. Wow, my body did not react well to that!

"It was like putting gasoline in a purified system," she continued. "I am always trying to eat organic and natural foods, so that just made my stomach turn and made me feel terrible. And I think what you put in your body, as well as stress, is reflected in the quality of your skin."

In the interview, Jennifer also revealed her tip to keeping her skin looking good.

"I can never stress enough to my friends that they must do as I do ... hydrate, hydrate, hydrate," she said. "Drink lots of water, get enough sleep, exercise, and eat a clean healthy diet, whenever possible."
