"Vampire Diaries" co-stars Nina Dobrev and Ian Somerhalder still have to work together even if they are no longer dating - which can make for some awkward moments.

Witness their most recent public appearance while promoting their show at Comic-Con in San Diego over the weekend. The pair, who called it quits in May, attempted to joke about the split.

According to E! online, Dobrev responded to an audience member's question about her character by jokingly asking, "Is there anyone Elena hasn't made out with?"

When someone else in the audience shouted, "Me!" Somerhalder replied, "Give me your number. I'll set you up."

Somerhalder's quip came just after the pair reportedly tried to avoid one another in the press room.

An insider told E! News, "Ian showed up and Nina showed up shortly after. She saw Ian was right in front of her and went away, then came back a little later so they were spaced out a bit more during press-line interviews."

The co-stars dated for several years before their breakup.

In an interview last year with Seventeen magazine, Dobrev, 24, admitted that she never wanted to date Somerhalder.

"I didn't want to be dating one of my co-stars - my goal on the show was to be professional," she said. "Sometimes you can't help who you have a connection with, and you can only fight it for so long."

Like art imitating life, Dobrev's Elena and Somerhalder's Damon, finally got together at the end of last season.
