If a recent prank war is any indication, Nina Dobrev continues to have a good time on the set for her new film The Final Girls. Check out the battle Vampire Diaries star has going with Vikings star Alexander Ludwig, who also happens to be working on the horror comedy. It’s vampires versus vikings — place any and all bets now!

Nina and Alexander have a battle of frights going on over at the Final Girls set, and Nina totally appears to be winning. Yesterday, she posted this Instagram video of herself popping out from underneath Alexander’s trailer while he was answering an interview question. “Byaah!” she yells, causing her big, manly co-star to jump and eventually cover his face in (adorable) embarrassment. “That just scared the s--t out of him,” Nina tells the camera once she’s climbed back out. We love the lengths this girl will go to perform a prank! And, given that Nina captioned the vid, “@alexanderludwig HA! In your face Biatccccchhhh. Scare Score- Dobrev 20. Ludwig 6. #MunchinWinning #VikingFail,” it sounds like she is owning the prank war. Alexander better pick up the pace. They only have a few days left on the Louisiana set.

We have a feeling that Alexander may be ready to throw in the towel. Yesterday, he tweeted: “Its already been real. Real embarrassing. @alexanderludwig: @ninadobrev has taken this to another level. I need back up. Its about to get real.” Might be a good idea, dude. As far as we can tell, Nina is awesome at everything she sets her mind to.

Nina re-tweeted one of Alexander’s recent tweets with news of her apparent win: “That is what Victory sounds like Xander... ‘@alexanderludwig: @ninadobrev is laughing like a little maniac right now...’” There you have it: vampires trump vikings.

Do you find this prank war as awesome as we do? Does it make you want to get Alexander Ludwig a role on TVD so it can continue? Sound off in the comments below!
