As the plane came into the gate the plane was not centered. The mains were not perfectly divided at all. The nose of the plane was forward of the mark. On the departure the lead started to push. As he was pushing I noticed the captain's  wing coming to close to the first officer's wing on the gate next to where I am wing walking. I held out my stop signal about 6 feet from impact. The push back driver of my plane did not stop until impact of both wings damaging both. I noticed the First Officer's wing of the gate next to me was taken off.
Ramp Agent reported the aircraft was pushing too close to the adjacent aircraft and attempted to stop the tug driver. The driver did not see him and ended up pushing the aircraft wingtip into the other aircraft's wingtip.
