The two co-starred together on the steamy supernatural drama "The Vampire Diaries," and it seems their romance extended off the set as well.
Nina and Ian began dating in late March 2010. They only confirmed to be together a year later, in June 2011, at MuchMusic Video Awards. Nina openly talked about her relationship with Ian for Seventeen in September 2012:
"I didn’t want to be dating one of my co-stars," Nina told the magazine. "My goal on the show was to be professional. But sometimes you can’t help who you have a connection with, and you can only fight it for so long — which I did for a really, really long time."
They broke up in late April 2013, after 3 years together. On May 9, 2013, it was confirmed that Nina and Ian weren't together anymore.
