On Thursday's much-touted joint interview with Jennifer Lopez and Ben Affleck on NBC's ''Dateline,'' Lopez said that she and Affleck were ''good friends'' when they shot ''Gigli'' in late 2001 and early 2002, while she was still newly married to second husband Cris Judd. She did not say when she and her costar became more than good friends. But in an interview published in August's Reader's Digest, J. Lo says she didn't sleep with Ben until after she'd separated from Judd later that spring.
In fact, she tells Reader's Digest, she and Judd were already having problems by the time she met Affleck on the set of ''Gigli'' (opening July 30). However, she says, ''to talk about that with another man wouldn't have been cool.'' If Affleck was attracted to her then, he kept it to himself, she says. ''I'm a very faithful person. If somebody had told me, 'Ben's attracted to you', I would have said, 'No, I wasn't raised that way.''
J. Lo says her third marriage won't go the way of her first two because she and her fiancé ''talk about everything [with] brutal honesty ... And when you do that nothing's left to chance.''
