Nina Dobrev and Ian Somerhalder Break Up Reason: Vampire Diaries Actress Dating James Marsden to Make Actor Jealous?

Nina Dobrev's controversial love life has been the subject of rumors following her breakup with co-star and real life boyfriend Ian Somerhalder.  Supposedly, Nina's three-year relationship did not end entirely, but recent reports contradict the claim; she's been spotted with other men.

An insider to OK! Magazine revealed that Dobrev was seen with James Marsden on a night out at the Cat's Meow, located on Bourbon Street. The source said that the two "did more kissing than singing," while another eyewitness from Hollywood Life said, "Nina thinks James is hot. They have met before and they did hook up and had a great time."

Prior to her romantic interest with X-Men actor Marsden, 40, Nina was seen on several occasions with Muse band member Dominic Howard. Previous reports from Hollywood Life stated that Dobrev, 25, and Howard, 36, were sighted at the Coachella Music Festival last April as well as at the Grand Prix de Monaco in May.

In an August 2013 issue of Cosmopolitan magazine, Dobrev mentioned that her breakup with Somerhalder was a defining opportunity. To quote her statement, "People aren't defined by their relationships. The whole point is being true to yourself and not losing yourself in relationships, whether romances or friendships... I need to know all those things before I fall for someone. I'm not a one-night-stand kind of girl. I'm a relationship girl," reported the lifestyle magazine.
