Ian Somerhalder  and Nina Dobrev  were the duo of the night at PaleyFest's event for The Vampire Diaries in LA on Saturday. The CW costars and former boyfriend and girlfriend sat next to each other during a chat about their show, resulting in a few can't-miss moments. At one point, Ian even reached out and held Nina's arm, as costar Paul Wesley  looked over at them. The interactions didn't stop there, though — the buddies also high-fived and leaned in as they pointed at the audience.
In January, Ian caused a stir when he kissed Nina  at the People's Choice Awards, following it up with a loving tweet. "The world loves you!" he wrote. The actors have also spent time together during their breaks from work. Ian linked up with Nina at her birthday party, where they took an adorable photo with Julianne Hough .
