Hollywood couple Heath Ledger and Michelle Williams were soaked on the red carpet at the Australian premiere of their new film Brokeback Mountain when a cheeky photographer sprayed them with a water pistol.

The couple were signing autographs and posing for photos yesterday (13JAN06) when the snapper pulled out an orange gun and sprayed them with water before fleeing the scene.

Other photographers, who were also sprayed in his candid camera attack, gave chase and apprehended the prankster in a nearby Sydney street.

Ledger, who has been known to lash out at the media in his homeland, wasn't going to let the incident ruin his big night, but he told reporters after the screening, "It's a little embarrassing. It's not the nicest send off before you go home."
