premise: As Mel Gibson walked hand in hand with his new Russian girlfriend on the red carpet last night, a few new grey hairs were the only sign that he is a man about to lose $US500 million. The Australian actor - in the middle of what is expected to become one of the world's most expensive divorces - attended a movie premiere in Los Angeles with Russian songstress Oksana Grigorieva, the woman at the centre of worldwide speculation about his marital split. The public debut of his girlfriend, at the premiere of X -Men Origins: Wolverine, put to rest the rumours which have dogged the Oscar-winning Braveheart star since it was announced he was divorcing his wife of 28 years, former dental nurse Robyn Gibson.
hypothesis: Mel Gibson comes from Australia.
