Madonna was at a pre-Mother’s Day dinner at Dirty French on Saturday.

The singer dined with daughter Lourdes, designer Marc Jacobs and pals, but son Rocco — the subject of her bitter custody battle with ex Guy Ritchie — wasn’t on the scene.

Madge “didn’t have security . . . She was just hanging like a normal person,” said a spy. But when a fan approached, “He asked for a picture . . . She said, ‘No, not now.’ He then asked her for a hug.”

But Madonna shot back, “How about a handshake instead?”
