The cast of The Vampire Diaries is incredibly tight-knit, and the drop-dead gorgeous Ian Somerhalder (who plays the undead Damon Salvatore) is no exception. Ian is close with all his castmates, and the group’s pretty much constant stream of tweets at each other is all the evidence we need. Admit it, the whole thing is pretty cute. 

Then a fan asked us who Ian’s real life best friend is, and we got curious especially after Ian Tweeted this cryptic message: “Happy Birthday to my friend and bro, you know who you are:) celebrate!”

So who is Ian Somerhalder’s bestie? Ian plays things pretty close to the vest, but here are some contenders! Top of the list has to be his co-star and real-life girlfriend Nina Dobrev, of course, but Ian and his on screen brother Paul Wesley also seem to be tight both on set and off, not to mention he’s incredibly close with his real life brother Robert.

 Another contender is Kim Klingler, the executive director of the Ian Somerhalder Foundation. You know Ian would only want someone he knows really well in charge of something so important to him!
 
Ian also officiated the wedding of his friends Paul and Jessica last year, and that’s not something you do for just anybody!  


Maybe his bestie is of the four-legged variety

 

In any case, it looks like Mr. Smolderhotter is in high demand!
