Hot chick selfie ruined by dude who might be a zombie

Aww, what an adorable selfie. These two girls are really cute, aren’t they? And that one kinda has great knockers and I think I love her and OH MY GOD, WATCH OUT BEHIND YOU.

Best guesses as to who/what that is, ranked:

1) Voldemort

2) Zombie

3) Kim Kardashian
