BRAD PITT - PARANOID PITT FEARED CLOONEY PRANK

BRAD PITT was so certain GEORGE CLOONEY and MATT DAMON were planning to pull a prank on him during the OCEAN'S ELEVEN shoot, it took him over two hours to scour his hotel room for booby traps every night.

The paranoid movie star spent sleepless nights in his Las Vegas, Nevada hotel room worrying about becoming the subject of an elaborate practical joke - after handing Damon the keys to his suite.

Pitt gave up his room one weekend for Damon's pals, and when Damon kept forgetting to give him the door key back, he grew nervous.

Damon recalls, "He had circles under his eyes and, for Brad Pitt, it's tough for him to look bad, so I was like, 'What is going on with you?' and he goes, 'You don't really get it.'

"He said, 'When I get home every night, the only thing that's going through my mind is that you and Clooney have my room key.'

"He goes, 'I'm checking the toilet for Surround-Wrap (cling film) on the top, I'm looking for buckets of water over the doors. It takes me two-and-a-half hours to get through my room to check for booby traps."
