How Stupid Are You, Sean Penn?

Sean Penn is in some major trouble with both the paps and cops.
The recently divorced actor may be slapped with battery charges after Penn reportedly lost his shiz on a paparazzo on Friday afternoon in Brentwood and assaulted the photog!!
The pap has since filed a report with the police, claiming the actor of battery.
Kicking and hitting a guy while there are a bazillion paps around????
Not the smartest idea.
