Travelers at Los Angeles' International Airport got quite an earful recently when Maria Conchita Alonso and Sean Penn traded verbal jabs at the luggage carousel. Screaming loudly, Maria called Sean "a communist," while he labeled her "a pig."

The root of the argument stemmed from the two stars' political beliefs. Alonso had publicly criticized Penn for appearing alongside controversial Venezuelan president, Hugo Chavez. Clearly Sean didn't appreciate her remarks and let her know it when they came face to face at the airport.
