i'm looking for the title of a french movie,i have already watched the movie but i want to know the title.it was a comedy about a guy with a bicycle,his girlfriend is pregnant and she calls him at her house to tell the news.But he is not the only possible father.Another man is there for the same reason.The girl demands from both of them to help her until the baby is born and that 's the beginning.
Can someone help me?
