English actor Orlando Bloom was reportedly sipping Patron XO tequila when Nina Dobrev came to his table. Witnesses told the New York Daily News that the pair "talked closely."

Witnesses told the New York Daily News that Bloom and Dobrev were "dancing very closely, flirting, laughing and whispering in each other's ears."

"Orlando is usually reserved, but he had his hands around her waist and he was dancing with her very closely. At one point, I really thought they were going to kiss," the Daily News' "spy" continued.

Nina Dobrev was at Comic-Con to promote "Vampire Diaries" with her ex-boyfriend Ian Somerhalder. The pair split up in May 2013. Ian Somerhalder has since been reportedly dating Twilight actress Nikki Reed.

Ian and Nikki, meanwhile hit the Comic Con after party at Hard Rock Hotel's Float Bar where, witnesses say they got "hot and heavy."

One source told E! News "They were so together." Another witness told E! News "they weren't hiding their PDA at all."
