Vampire Diaries star Ian Somerhalder (Damon) is a popular guy. So popular, in fact, that he is only one degree of separation from Kevin Bacon. Check out the photo evidence!

“#TheFollowing + #TVD #SXSW2014 mashup! MT @Naira_TVD: @kevinbacon &  @iansomerhalder #sxsw,” Chris McLaughlin tweeted two days ago, along with a photo of Ian and Kevin with their arms around one another.

This marks a total TV mash-up, given that Kevin now stars as former FBI agent Ryan Hardy on Fox’s The Following. Coincidentally (or maybe not), both The Following and TVD have Kevin Williamson as a creator, and this isn’t the first time we’ve seen a TVDer hanging with a member of The Following’s stellar cast.

Last month, Nina Dobrev (Elena) built a snowman with Shawn Ashmore during downtime on their photoshoot. It may be time for a full-on TVD/The Following crossover. At least one of TVD’s characters has to be less than six degrees of separation from one of The Following’s. Might Ryan Hardy secretly be a vampire?

We totally love Kevin, and his honesty. According to CNN, Kevin recently admitted at the South by Southwest Festival that he disliked the classic parlor game, “Six Degrees of Kevin Bacon,” which is a play off of the idea that everyone is only six relationships from everyone else.

However, the Kevin Bacon version is transposed onto film stars. "I was horrified by it. I thought it was a giant joke at my expense," Kevin said. "I appreciate it now. But I was very resistant to it (at first)." And how do you feel about TVD, Kevin?

Catch the next episode of The Vampire Diaries on Thursday, March 13 at 8 p.m. ET on The CW.
