French actress Julie Delpy has hit upon the major differences between men and women in love - girlfriends like to hear tales about their predecessors, while boyfriends would prefer to think they're the first.
The pretty star used her relationship studies to inform her new movie 2 Days In Paris, which she wrote and directed, and admits she's often amused by the differences between courting couples.
She says, "I don't mind that my boyfriend (composer Marc Streitenfeld) had another girlfriend. I want him to tell me stories actually. I kind of like the idea.
"I'm kind of more intrigued, girls are more intrigued.
"Guys, they don't want to hear about it. They don't want to know that there was other men. Men don't like to know that there's been someone else at that place, that conquered property of theirs."
