Ian Somerhalder and Nina Dobrev: 10 Years
Vampire Diaries co-stars Ian Somerhalder, 35, and Nina Dobrev, 25, had a seemingly unbreakable relationship for a couple of years. Back in September 2011, Ian gushed to Us Weekly, “[Nina] truly enjoys life. Her desire to experience and appreciate everything around her, and chuckle and enjoy it, is great.”
Sadly, their fictional characters being bound by fate wasn't enough to keep their real-life counterparts together! The pair split in June 2013, but they still work together and have "enormous amounts of respect" for one another.
