Ruby Rose and Nina Dobrev battle it out in a prank war

There is a war brewing on the Toronto set of xXx: The Return of Xander Cage and both sides refuse to back down. The film’s leading ladies Nina Dobrev and Ruby Rose are figuring out ways to one up each other in a good old fashioned prank battle. So far both actresses have pulled off some memorable jokes after Nina kicked off the competition last week.

“ThoughtIWouldnt #ButiDid #GotHer,” wrote Nina on Instagram, alongside a video showing her jumping out to scare Ruby when she entered her trailer. The 27-year-old signed her post with, “Game on.”

Not one to let a prank go unanswered, the Orange is the New Black star plastered photos of herself all over Nina’s trailer and documented it on social media for the world to see. “When you go to say hi to Nina Dobrev but she has 100 photos in her trailer of you and it’s awkward because you’re trying to be professional.” The actress even joked by writing, “#seekhelpnina,” and “#ineedextrasecurity.” The ball is now in Nina's court.

The duelling duo have become fast friends on the set the latest flick in the xXX franchise, which stars Vin Diesel as an extreme athlete turned government operative. Toronto-native Nina has taken her role as host seriously by showing her colleagues around local hotspots and organizing a group game of archery tag. The latter was also enjoyed by Nina's close friend Julianne Hough, who was up in Toronto over Easter break to visit her Toronto Maple Leaf fiancé Brooks Laich.
