There is a great story in a Brazilian newspaper about Megan Fox and the way she behaved during Carnival in Rio. She was paid a ton of money to appear at events for Carnival. More money just to show up than most of us will ever make in a lifetime. That event was in front of huge crowds and everything was fine because she was getting paid. Later on her visit she was headed to a restaurant and there were big crowds in the streets and she thought they would recognize her so she hid all the way on the floor of the car and started crying and screaming. No one had noticed her and no one would have cared. When she got to the restaurant, there were paps there. They were there because there were a lot of celebrities in town and most usually go to this place at one point or another. Megan saw them and thought that they were all there to see her (which they weren't) and ordered the driver to turn around and went back to the hotel. (Thanks Luciana)
