This A list mostly movie actor was making out and groping some woman in a corner of a Vegas hotel the other night. The woman looked scarily similar to the actor's sister. So much so, that the person who spotted the actor had to do a double take because he thought something really juicy was going on. Well, the pair are close, so it would make sense he would find someone who looks like her. Just as long as he is not calling her sis in bed or something.
