After denying for a long time that they were dating, and after being seen together on a Mexican vacation, Sean Penn and Scarlett Johansson have practically made it official. Well, not exactly, but the newly divorced Penn and the almost-divorced Johansson have been seen holding hands, which must count for something...

Well, until we know for sure whether 24 years of age difference is too much even for Hollywood, here's a quick 6-degrees-of-seperation game. Actually, guided by The Oracle of Bacon site, we can do it with only three degrees, even if they are helped by an actress with a very minor role in two of the movies...
In 2004, Johansson played alongside Colleen Camp in In Good Company.

Two years earlier, Camp played with Bacon in Trapped.

Between these two movies, in 2003, Sean Penn played with Bacon in Mystic River.

There you go. It took 9 years and three degrees of separation, but finally... Well, at least they're holding hands. Although if it gets better, they should really thank Kevin Bacon.
