Charlize Theron shoots secret nude scene at dawn

Monster actress Charlize Theron is apparently a little shy.

The Hollywood star filmed a nude scene in her latest movie at dawn to avoid prying eyes - and camera lenses.

The scene for new movie, The Burning Plain, was shot in Portland, Oregon, and saw Theron standing naked while smoking a cigarette through an open window.

"We had to shoot at 6am before any of the photographers were up," revealed director Guillermo Arriaga.

"It was done in such secrecy that it wasn't even in the script.

"Only three people, including myself, knew it was going to happen."
