Ian Somerhalder’s rumored new romance appears to have lit a fire under Nina Dobrev, the actress reportedly seen flirting with three actors while attending Comic Con 2014 in San Diego this past weekend.

After appearing alongside Somerhalder, ex-boyfriend of three years in a panel for their hit CW series “The Vampire Diaries” at Comic-Con Saturday, Dobrev, 25, was reportedly spotted getting cozy with some of Hollywood’s leading men including newly divorced “Pirates of the Caribbean” star Orlando Bloom and TV actors Benjamin McKenzie and Derek Theler.

“Nina has known Orlando for a few years now. She’s been out with him in social setting with mutual friends,” a source told US Weekly after the pair was seen flirting and dancing at Zachary’s Levi’s #NerdHQ party July 26. “She’s always thought he was an attractive man.”

While Dobrev was seen getting close with Bloom, 37, who split from his wife, model Miranda Kerr last fall, the actresses most buzzed about flirtation occurred with actor Derek Theler.

According to a report from HollywoodLife, Theler, 27, of ABC Family’s “Baby Daddy” fame, shared a kiss with Dobrev while attending Entertainment Weekly’s 2014 Comic-Con Celebration at the Hard Rock Hotel’s club Float.

“The kiss from the ‘Baby Daddy’ guy was in the moment and out of nowhere, liquor-enabled kiss,” a source told the gossip site. “No tongue or no major passion.”

While the actor’s kiss may not be indicative of a future Hollywood romance, eyewitnesses did report that Somehalder, 35, was also in attendance at the soiree, “sweetly and passionately” kissing his rumored new girlfriend, “Twilight” star, Nikki Reed, 26.

Despite engaging in PDA with Theler, Dobrev’s night ended with “Southland" star Benjamin McKenzie. While Dobrev was seen entering Entertainment Weekly’s bash with her co-star, actress Kat Graham, photographers captured Dobrev getting cozy with McKenzie, 35, outside the party, later leaving together in the same cab.

Since her split from Somerhalder in June 2013, Dobrev has been linked to “Dancing With the Stars” professional Derek Hough, Liam Hemsworth of “The Hunger Games” film franchise, “The Vampire Diaries” Michael Trevino and “Captain America” actor Chris Evans.

Catch up with Dobrev and Somerhalder on Season 6 of “The Vampire Diaries” premiering this fall on the CW.
