Paul Wesley and Phoebe Tonkin seemed to have a pretty haunting night before Halloween.

Phoebe Tonkin Gives Paul Wesley An 'Innocent' Back Massage

The couple stars in two separate CW series The Vampire Diaries and The Originals so they're already used to being a part of the sinister environment involving bloody storylines with a strong dark side. So the two decided to go on Instagram to post photos of how they spent the night before the spookiest day of the year.

In Tonkin's photo, she works on set where a dark sky can be seen in front along with deep water. As the trees loom over, a camera crew can be seen in the back as the actress has fun with "night shoots."

As for Wesley, he seemed to have a dreary night as well where a camera shows someone walking on the side of the street underneath a black sky.

It's unclear what the two have planned for Halloween night, but odds are they'll do something pretty fulfilling. The two seem to enjoy their morbidness on the series they star in since Wesley's been a part of his vampire series for so long. Tonkin also happens to get pretty enthusiastic behind the scenes.
