Ian and Nina met back in 2009 when they started filming The Vampire Diaries together and dated for three years before breaking up in May 2013. Despite their split, the two continued to work together on The Vampire Diaries and have remained friends.
In 2015, Nina opened up about their relationship, telling E! News, "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."
