Madonna was spotted with a mystery man — who resembled French artist JR — at Megu on Wednesday.
“They were acting like a couple, chatting and laughing closely in a corner” of a private room, a spy said.
Madge’s son Rocco interned for the artist in 2014.
JR’s posted several images of the Material Girl on Instagram, and she recently included a shot of them together with a cryptic message. “Sometimes you just have to take off the mask and confess!” she wrote.
Her rep did not comment.
