Clooney talked about his prank war with his close friend Brad Pitt during a chat on "The Graham Norton Show". The 54-year-old "Tomorrowland" actor said he may have crossed the line with his latest prank and could get arrested for that, reported Ace Showbiz.
"I'm doing one now that I can't tell you about but in a year you are going to hear I've been arrested - I'm not kidding because I think I've crossed the line," Clooney said.
But he's not nervous about the potential legal trouble. "I have a wife, she's a barrister, I'll be fine!" he said.
In another occasion, Clooney put "a bumper sticker in the shape of a pot plant in Pitt's car, which resulted in the latter getting pulled over by police.
