Pennman????

Natalie Portman, the 27-year-old actress, is firmly denying rumors that she and reigning Best Actor Sean Penn are an item.

"Sean Penn is a friend and colleague," the star of the upcoming New York, I Love You said in a statement to Extra Friday. "The reports that we are romantically involved are completely untrue. I normally do not respond to rumors about my private life, however, this repeatedly fabricated story has forced me to do so."

Sounds guilty to me!!!!!!
