The photog suing James Franco says he has hard proof the actor gave him the ole cabeza to the gut … and we got the pics.
Aria Miran of RMD Law firm says these shots show James charging head-first at his client, David Tonnessen … and they’ll be the primary evidence used in their lawsuit.
We broke the story … David says he was taking pics at a Lana Del Rey concert 2 years ago when James smiled “rather demonically” before unloading the head-butt. Now he’s suing for medical expenses and damages.
James’ people haven’t gotten back to us.
