Hollywood Rules
Meaningless bunk up: Scarlett Johnasson plays house with Sean Penn, but itproves little

Sean Penn and Scarlett Johansson
Hot on the heels of rumors that she's pregnant, recent divorcee Scarlett Johansson is dealing with a new piece of gossip: That she's moved in with her much-older and very famous boyfriend, Sean Penn.
But in Hollywood, what does "moving in" even mean? That Johansson's shacking on the reg? Who cares?
Still-married Courteney Cox and David Arquette are in separate houses. And when Sandra Bullock divorced Jesse James, she moved back home — into the separate residence she had maintained throughout their union. By Hollywood standards, how serious is moving in, really?
Celebs routinely keep their bachelor and bachelorette pads (Helena Bonham Carter and husband Tim Burton, though they happily share children, still only share an adjoining door), they travel constantly and their homes are so sprawling that they could easily coexist with a live-in slam piece in relative piece, if not total oblivion to their presence.
Among real humans, the first couple's getaway is a big step. In Hollywood, relationships are confirmed over first dates in Cabo San Lucas.
Tell us: Do you think Scarlett shacking up with Sean means there's something serious going on? Or is it just another case of the tabloids making a mountain out of a molehill?
