Celebrity couple Jennifer Lopez and Marc Anthony have made a pact never to speak about their fans - in case it makes them jealous. Lopez, 38, claims fans' constant admiration of the pair is putting a strain on their marriage. She says, "Girls from 18 to 80 all love him, but we make a point of not going there. I don't talk about that kind of thing either because it just wouldn't be a good thing. "It would be like, 'Ooh, that guy in the front row was really looking at me tonight'. It wouldn't be very nice."
