Can someone help me find this weird movie?

I know this is going to sound strange, but I think it was a couple made up of a blond guy and a girl who I believe prostituted themselves together. I remember a scene where the guy is having a photo shoot in the woods while he is semi-nude. I’m not sure if it was in a forest or just in darkness, but I remember that at the end the two protagonists have a scene where they reconcile, but it turns out to be the imagination of one of them who is in a taxi, and in the end they do not end up together. I’ve tried to describe it as best as possible, sorry haha.
