I'm going to assume it's either someone he knows IRL/outside of MSP or that it hasn't been and most likely will not be disclosed.
I'm sure you all can imagine what would happen if it was another moviestar and her(or his? do we know it's a she?) name was brought to light.
Regarding me questioning the gender, I know mybeau said "other girlfriend", but I don't know if we can trust her or his(packers) word on that. I'd rather just be on the safe side.</small?
