"They looked relaxed and seemed to be having a fun time together," an eyewitness tells PEOPLE. "Like a dating couple, they always walked very closely, holding hands and their arms touching side-by-side."By 'eye witness' I wonder if they mean the dude who sells balloons to the kiddos? ha-ha
The two recently filmed the drama The Place Beyond the Pines together so it really doesn't surprise me that they're 'doing it'. Most of all stars that star together in a flick end up hooking up. I don't see this one ending in marriage, mostly because Eva once said she didn't believe in it but I guess the right guy with the right six-pack could change that.
