I rack my head about a scene and I don’t find out the movie it is from.

I think it was a romantic comedy where a man and a woman finally get together after the usual back and forth. Somewhere in the movie, maybe at the end, they argue about their future and how it will be once they are married. I only saw the German dubbed version, but the man says or yells something like "Not that you will sit on the couch all the day long, eat tons of chocolate, and become fatter and fatter!” and she yells back “And you, not that you will grow your last remaining hair, make a skein out of it, and wrap it around your head like a turban!” while she moves a hand around her head in circles to illustrate what she means.

At least that’s how I remember the scene. I thought it would be from “When Harry met Sally…” but I recently saw it again and the scene was not in there. Nevertheless, I remember her as being blond with a short or at least not so long hairstyle. The acting would also fit to Meg Ryan, I would say. When she moves her hand around her head, she does so very vigorously and makes a funny face. I also thought about Kate Hudson or even Helen Hunt. However, I looked at scripts of their films and didn’t find anything in that direction. Maybe she does not say turban in the original version, but it presumably must be something very similar due to her mimicry.

I know, it's not very much what I know, and what I know is very vague, but maybe anyone can help anyway...
