This is who Arnold Schwarzenegger cheated on his wife with?

Come on guy, you are the Governator and you threw away your marriage for this?  I'm not even sure this is a real woman.  She looks like a the villain in a Superman Comic.  I am not even sure why this lady wasn't cast as Thing in the Fantastic Four movies, she wouldn't have even had to put on the rock suit.  She already looks like a rock monster.
