The "Vampire Diaries" star Nina Dobrev is said to be romantically involved with actor and director Mark Kassen.

Nina Dobrev has shared a number of photos during Thanksgiving which includes Mark, speculating the rumors that they have been secretly dating for months.

According to International Business Times reports that rumors are flying around that co-star and ex boyfriend Ian Somerhalder is extremely jealous of Nina finding love somewhere else.

However, the parties aforementioned haven't confirmed any such news. But fans shouldn't expect an official statement anyways because Nina Dobrev is not forthcoming much and prefers to keep her personal life away from gossip columns.

Apart from few episodes of "The Vampire Diaries" in the future, these rifts has caused IIan Somerhalder and Nina Dobrev to not share the screen any time soon.

Rumors suggest that Nina quit the "The Vampire Diaries" because of Ian breaking up with her and then flaunting his relationship with "Twilight" actress Nikki Reed on Nina's face. This has caused much tension between Nina and Ian.

Nina has clarified her views about Ian in an interview with E! saying, "I've said this before, that we didn't break up because anything bad happened or because there wasn't love or friendship."

"I love him and the friendship is still strong and I think he's great and I care about him. And that didn't change. Yes, we're professional and that's fine. We were friends long before we dated and we still are now."

According to The Bit Bag, the reason Nikki Reed has gotten herself pregnant is because she wants to save her marriage with Ian Somerhalder. Even Nikki Reed is concerned about Nina's past relationship with Ian as well.

Ian Somerhalder and Nina Dobrev fell in love on the sets of "The Vampire Diaries" back in 2009 and they were together till mid-2013.
