BRAD PITT - PITT AND CLOONEY INCREASE SECURITY FROM STONED FANS

Hollywood stars BRAD PITT and GEORGE CLOONEY are increasing security on the Amsterdam, Netherlands set of OCEAN'S TWELVE - to prevent stoned fans from harassing them.

The actors are being shielded by minders from cannabis-crazed fans as they venture out in the Dutch capital, where the drug can be smoked legally.

Another star of big-budget Hollywood follow-up, MATT DAMON, has already been accosted by two men from Liverpool, England, as he roamed round the city with his girlfriend LUCINA BOZAN.

A source on the set says, "The lads were out of their heads. They stopped to ask Matt for directions and got a bit aggressive when he couldn't point them the right way."
