Paris

The idiot who wrote the question thinks the tower behind is the Eiffel tower

What has that got to do with where they were born? So if they took a bathroom selfie they were born in the toilet?

Are...are you actually that stupid? @nylonbase

The facebook commenter asked if the girls in the photo were born in Paris, because it appears that (I'm not saying I agree with this) the Eiffel Tower is behind them. That's all it is.
If you can't get this, you're either a moron or a stubborn troll.
