Gossip: Natalie Portman, Sean Penn

Natalie Portman this week denied that she is having an affair with the recently single Sean Penn. “I normally do not respond to rumors about my private life,” said the 27-year-old Portman, “however, this repeatedly fabricated story has forced me to do so.” The two actors have reportedly been seen together several times since Penn, 48, separated from his wife, Robin Wright Penn.
