My boyfriend is an alien who flies around in his underwear with the cape his mom made him so its going to take a bit to freak me out. It did take me back a step at first, but it more so piques my curiosity more than anything. Face twin thing still can be creepy on occasion but I'm more weirded out by the women in my immediate family all playing versions of me in different media. Not that it stops me from watching that particular show.
Do you know what her name is? Because you can probably track down the list of movies or whatever that the actress with your face plays in so you can avoid them.
