Things are heating up between Ian Somerhalder and his new rumored girlfriend Nikki Reed. The pair attended a Comic-Con after party together on Saturday, July 26, and sources said Somerhalder and Reed were getting pretty cozy with each other.

According to E! News, the 35-year-old "Vampire Diaries" hunk was seen kissing and holding hands with the "Twilight" actress during Entertainment Weekly's bash at the Hard Rock Hotel's Float Bar.

"They were so together," the source told E!.

Another source added that Somerhalder and Reed "were hot and heavy," and "they weren't hiding their PDA at all." It seems like Somerhalder and Reed may be ready to go public with their romance. The source told E! that things got a bit awkward at the EW party because Somerhalder's ex, Nina Dobrev, was also in attendance.

However, onlookers said the trio did not run into each other at the Hard Rock and Dobrev ended up skipping out with Ben McKenzie. The night before EW's party, sources claim the actress was seen "flirting" with Orlando Bloom at Playboy and A&E's "Bates Motel" event.

Somerhalder and Dobrev split last year, while Reed and her husband, Paul McDonald, divorced in March.

"Nobody had any idea they knew each other," a source told E! speaking about Dobrev and Bloom. "They seemed connected like magnets. They were canoodling; he had his arm around her."

A source previously told Hollywood Life that Somerhalder and Reed were trying to take things slow and not rush into a relationship because they don't want to ruin their friendship.

"They are really tip toeing into something. They are trying to see if their friendship can be more, but it is at its infancy," the source said. "They are really taking things slow because they don't want to ruin their friendship, but there are also feelings between the two."
