Julia supposedly meeting with Mylène and Laurent at "Brasserie Mollard" in Paris. This was posted on Julia's Instagram Story yesterday (May 11th). Some Fans think they may have identified their voices in the background.
Video with subtitles.
(Laurent) mentioning "Woodkid" may be a reference to Mylène's currently in the works upcoming 12th studio album. His name has been suggested as a possible collaborator.
