Jude Law claims American women find British men irresistible because of the"naughty" words they use.The British actor believes the quaint vocabulary used in his homeland get American ladies' pulses racing. He said: "Perhaps it's the use of words. We use words like 'lovely', and 'naughty'. I think they quite like that."The father-of-three also says he has accepted the fact he will always be regarded as a heartthrob. Jude, 34, told the New York Daily News newspaper: "It's a silly situation because it's always, 'Grass is greener'. When you're called one thing, you want to be understood as something else, and if you're called the other thing, you want to go the other way. But I think the beauty of getting older, not ageing, because I'm not that old, is that you just mellow out and realise that to be called anything means people are paying attention."Last month, Jude visited Afghanistan in a bid to promote world peace.The 'Cold Mountain' star travelled to the war-torn country to film a documentary about the United Nation's Peace Day on September 21. Jude visited British troops, UN diplomats, Afghan government ministers,village elders and "many, many children" during the trip.
