George Clooney has slammed the current trend for posting mobile phone videos of celebrities in embarrassing situations on the internet.
The Syriana star insists stars have to watch their every move in public because there's always someone watching.
He says: "It's not that actors have all gone crazy, it's that there are just so many different sources now.
"You know, everybody's got a camera on their phone now so, all the time, any mistake that anybody makes, you're going to have it on film.
"And boy, there have already been some dumb mistakes."
