Well costumes can be fun for everyone. This actually happened the night prior to Halloween, but costumes were still worn. Our B list actor who used to be an A list action hero was at a party with someone everyone assumed to be his girlfriend. His girlfriend is somewhat, but not overly famous, but this person was wearing a Sue Storm from Fantastic Four mask so no one could tell. Throughout the night the pair spent more and more time groping and kissing in a corner and on a couch and less time mingling. It was during one of these makeout groping sessions later in the evening that the mask slipped off the woman and it was discovered our action star was with another guy.
He is having quite the comeback lately and is definitely back up to A. He has a child. Connection to Ben Affleck.
