After getting into an argument with a female airport employee and balking at going through the security line, Sean Penn was taken aside at TSA officials today before jetting out of LAX. While being patted down, the Oscar-winning actor was on his best behavior, and after he made his way through the line just like everyone else, we're hoping he continued to mind his manners.

Though that would be quite entertaining...After being romantically linked to Scarlett Johansson this week, the latest hookup rumor is that Sean and longtime pal Charlize Theron are an item. Though sources told the National Enquirer that the two were spotted in the Chateau Marmont garden "totally drunk and on each other," insiders close to both actors laughed the claims off.
