AceShowbiz - What started off as a pure friendship on the set of "The Vampire Diaries" turned into a romantic relationship for Nina Dobrev and Ian Somerhalder. The two became good friends after starring on the series together, but eyebrows started to raise about the potential hook-up alert between them after they spent time at the Daintree Rainforest and the Great Barrier Reef together back in 2010.

As the rumors started to swirl, Nina was quick to pour cold water to the speculation by insisting that she wouldn't date her co-stars. But with their continuous loved-up displays, it was only natural that people didn't flat-out believe what she said and kept speculating they were dating. Just like what everyone had suspected for more than a year, Nina finally admitted to being romantically involved with Ian in a magazine interview, though they later broke up in 2013.
