Jennifer Lawrence "peed in the woods" whilst filming 'The Hunger Games'.

The 21-year-old actress - who plays heroine Katniss Evergreen in the movie adaptation of Suzanne Collins' book trilogy - admits she was so desperate for the toilet she relieved herself in the bushes.

She said: "I peed in the woods. But there's only portapots around and we're in heavily wooded areas. I was in the woods and we had disposable toilet paper.

"I was raised peeing in the woods!"

Keeping the confessions coming, the former Oscar-nominee says she often skipped showers while on location.

In an interview with 'Unscripted' she confessed: "We were shooting long hours and sometimes I would show up with the same blood and dirt on from the day before because I was tired. So I didn't shower, I wasn't very clean."

But there were more dangers on the Transylvania County set than just poor hygiene.

Jennifer told the Chicago Sun-Times newspaper: "There were bears there and lots of them, including mothers and baby bears.

"There were also wild turkeys, who were funny. We had an assistant director who had to run around and scare the turkeys away. But after awhile, they weren't scared of him anymore."
