It looks like things are starting to get steamy between Ian Somerhalder and his new rumored girlfriend Nikki Reed.

After being spotted out together last weekend the duo reportedly packed on the PDA when they attended a Comic-Con after party on Saturday night.

According to E! News, the 35-year-old "Vampire Diaries" season 6 cast member and the 26-year-old "Twilight Saga" actress were seen kissing and holding hands inside of the Entertainment Weekly party at Hard Rock Hotel's Float Bar.

An onlooker said, "They were so together." Meanwhile, another source said that Somerhalder and Reed "were hot and heavy," adding that "they weren't hiding their PDA at all."

This could have been an awkward situation seeing as Ian Somerhalder's ex-girlfriend, Nina Dobrev, was also present.

However, the pair managed to avoid the CW starlet inside the bash. Although the costars split back in May 2013, the two used to go on double dates with Reed and her then husband Paul McDonald. The actress split from the "American Idol" contestant back in March.

Meanwhile, it seems Nina Dobrev wasn't too bothered by the new couple as she was spotted at the EW party with Ben McKenzie where the two left the party in a cab together. The night before that the brunette beauty and Orlando Bloom were spotted "flirting" at The Playboy and A&E Bates Motel event.

While there was no kissing there was plenty of laughing and flirting going on between the two. A source revealed, "Nobody had any idea they knew each other. They seemed connected like magnets. They were canoodling; he had his arm around her."

However, this doesn't mean Dobrev will be calling Bloom her boyfriend anytime soon. An insider said, "Nina is loving single life," adding, "She is definitely enjoying herself right now."
