Very effeminate?
I was almost positive he was gay or bi, then I found out he had been with Mai-Linh Lofgren for quite awhile and was blown away. I know he's an actor, but he fit that alien like part in Men in Black 3 very well.
It's just his small stature and somewhat effeminate features; such as, his soft voice, smooth skin and shiny eyes. He even reminded me of Liza Minnelli at first glance ;0 lol
