Yesterday a Chinese fan spotted her at a Chanel store, and today Jolin posted these 2 pictures on her Instagram:
In the first one she's in front of the Grand Palais!
We don't know why she's in Paris at the moment. By the way it might be a coincidence (I don't think it is though), but MUSE's marketing, creative, image & art director Jimmy Chou is right now in Paris as well... So in my opinion Jolin is in Paris for work.
