Nina Dobrev [1] and Ben McKenzie shared a passionate embrace at Entertainment Weekly's Comic-Con party in San Diego on Saturday. As Ben wrapped his arms around Nina and held her head, she rested her chin on his shoulder and held his lower back. Later, Ben and Nina exited Float Bar at the Hard Rock Hotel and hopped in a taxi together, igniting rumors of a romance between The Vampire Diaries actress and Gotham actor, who rose to fame on Fox's The O.C.

Ben wasn't the only man who spent time with the brunette bombshell on Saturday — according to reports, Nina kissed and danced with actor Derek Theler [2]. Meanwhile, Ian Somerhalder [3], Nina's ex-boyfriend and costar, reportedly shared PDA with their longtime pal Nikki Reed [4] at the same party. All the romantic moments come one week after Ian showered Nikki with affection [5] at the farmers market in LA. Ian and Nina ended their three-year relationship [6] in May 2013 but have remained friends. In January, the former couple stole the spotlight at the People's Choice Awards when Ian planted a big kiss on Nina's cheek [7]. Scroll through to see Nina and Ben's first pictures together!
