If you've already seen the new version of IT, you'll be aware that the new Pennywise the Clown, played by Bill Skarsgard, is pretty damned terrifying.

Even if you didn't think you had a fear of clowns previously, you did after watching that film.

Needless to say, the last place you'd expect ol' Pennywise to turn up is in your engagement photos - but not if you're Jesse McLaren's sister.

The photographer's sister asked him to shoot some pictures with her new fiance, but the trickster photoshopped the evil clown into them without her knowing, saying 'Countdown until she notices'. We're pretty sure that she noticed quite quickly, as a murderous, child-eating clown is difficult to miss - but nevertheless, Jesse, you're a bad person.
