Hollywood has a new couple, and the rumor mill is claiming that it is Nina Dobrev and Ruby Rose.

According to Celeb Dirty Laundry, the 27-year-old Bulgarian-Canadian actress and the 30-year-old Australian model-recording artist-actress have been spotted spending more time with each other while taping for "'xXx: The Return of Zander Cage."

The report noted that the closeness of the two seemed undeniable considering that they are comfortable playing pranks on each other.

And the fact that "The Vampire Diaries" star and "Orange is the New Black" cast member are currently single, it is reportedly not impossible for them to be romantically linked with each other. It can be recalled that Nina Dobrev called it quits with Austin Stowell earlier this year after her failed romance with Ian Somerhalder, while Ruby Rose called off her engagement with Phoebe Dahl in December last year.

Amid this rumor, Celeb Dirty Laundry commented that "Maybe Nina is taking a break from guys. Maybe she's just making some new friends on the set of the movie."

In the meantime, "The Perks of Being a Wallflower" actress was said to be full of good words only for the former "Australia's Next Top Model" co-host during an interview with the "New York Post."

"Ruby is a force to be reckoned with, and I am beyond lucky to have her as a co-star and to be able to call her a good friend," she reportedly told the news outlet. "She's hard-working, focused, funny, professional, fiercely determined and a lot of fun to be around."
