Despite their split Ian Somerhalder and Nina Dobrev are back together... on the set of their hit show "The Vampire Diaries" that is. The actors returned to Atlanta last week to begin filming season 5 of the show.

According to the Examiner, on July15th Somerhalder took to his Twitter account and made followers wonder if he misses his ex-girlfriend.

The actor tweeted a somewhat cryptic message that seemed to be directed towards something or someone in particular and we are just going to jump to conclusions and say it was about Nina Dobrev.

The actor said, "Aloneness is a state of being, whereas loneliness is a state of feeling. It's like the difference between being broke and being poor."

The tweet is out of place compared to the other happy tweets the actor has written when he was on the other side of the world and didn't have to work about bumping into his ex.

The Examiner reported that both Dobrev and Somerhalder have been cordial on set seeing as the really have no other choice.

Since the show wrapped its fourth season the former couple has not had to see each other for the past couple of months but now they are forced to take a good look at each other everyday while on set.

A source told Celeb Dirty Laundry that the two are doing their best to try to make things work, "Nina and Ian are back in touch after several months spent apart. [But sparks aren't flying. It just] means that they are doing everything possible to keep things as least awkward as possible."
