Who says exes have to be awkward around each other??
They hugged, posed for pics together, and then went about their business!
But with another super seXXXy man giving his lady free hugs, we hope Justin Theroux didn’t get too jealous!!
Actually, we take that back. We hope he DID get jealous, jealous enough to lock down some official wedding plans!!
Jennifer hugging an ex is definitely something to get jealous of, Justin!! LOLz!
