Ian Somerhalder and Nina Dobrev are pros when it comes to hiding their romance, but it looks like the cat might just be out of the bag. A photo has been circulating the internet since the weekend and it looks like The Vampire Diaries co-stars locking lips!

The photo shows two people kissing and if you look closely, it definitely looks like Ian and Nina. Fans of the duo have been going crazy over this picture, but is it definitely the actors? It's unclear where the photo was taken but it looks like there is a baby bottle in the picture, which is totally random.

Ian Somerhalder and Nina Dobrev are very close, but whether their relationship goes beyond "just friends" is still up for discussion. The photo in question will be analyzed by every fan and while some are convinced it's them, others are still skeptical. Do you think the photo is really of Ian and Nina? What gives it away?
