Narrative:
Released brakes after coordinating with pushback crew. He was apparently listening to ATC because he began to push before the first officer relayed the pushback clearance to me. I asked him if he was listening to ATC and he confirmed this. I told him this was very dangerous and reminded him that his instructions to push must come from the cockpit and not from overhearing the ground controller. As this is a safety issue; we reminded him to file a report. He was unclear what this meant so we told him to ask his supervisor.
