What does Scarlett Johansson have in common with Sean Penn, a man nearly twice her age?
Quite a bit, it turns out, but romance isn’t a part of it, according to the actress’s rep.
“Scarlett and Sean are not dating – they have been friends for years. Nothing more, nothing less,” her rep says. “They have been talking over the last few months regarding Haiti Relief and Scarlett’s upcoming trip to Haiti as Oxfam’s Global Ambassador.”
