Melbourne, Apr 15 : Actor Mel Gibson's divorce battle is likely to be Hollywood''s most expensive and quickest one.
According to the lawyers, divorce could settle within months although the couple will remain married until October.
Gibson's wife Robyn filed for divorce in Los Angeles court citing "irreconcilable differences".
Since there is no pre-nuptial agreement signed ahead of their 1980 marriage, under Californian law she is entitled to half of her husband''s wealth.
