It's Bella Thorne and her boyfriend Tristan Klier! They decided to go as vampire bride and groom to go to Just Jared's Halloween party.
The idea is a great one for a costume! You'd just have to find a white dress, something to use a veil, and some eyeliner and blood red lipstick. The vampire touch is easy to add - add some pointy fangs, a little bit of fake blood, and draw on some bite marks on your neck.
What do you think of Bella's Halloween costume idea? What are you going to dress up as?
