yes it was. It turns out that the first scenes shot were before angelina turned up on set, and that brad and vince were the only ones there for a few months. apparently, jen and vince really hit it off when brad was filming were seen hanging out together in the trailer long before angelina was even a twinkle in brads eye, and that supposively made brad jealous.
who knows whats true.. but they've been talking about how jen and vince were actually cozying up on set before the divorce (or brangelina ) on all of our radio stations here in boston.
