Not only does vampires Bella and Edward have a strong love connection in "The Twilight Saga: Breaking Dawn Part 2," the actors of the main characters also have a strong love, only it's human.

Kristen Stewart and Robert Pattinson share a special bond on and off screen. They are real life boyfriend and girlfriend. They have been together ever since they met in 2008 in the first film, "Twilight," in the series, written by Stephanie Meyer.

The couple couldn't keep their hands off each other at Comic-Con 2012 San Diego on Thursday, July 12, where the "Twilight" panel took place, according to Hollywood Life.

They looked "so in love." Eyewitnesses said that the two real-life lovers were "snuggly" during the 7-minute preview clip for "Breaking Dawn Part 2."

One fan, known as @Terri_Schwartz on Twitter said, "Spotted: Kristen and Rob holding hands outside #mtvsdcc headquarters after the livestream. One, two, three awwwwwww."

Another super fan, @tashpalo, added, "Oh oh did you hear how Rob and Kristen were very snuggly while the footage was showing? Well the room was dark and from my POV, Kristen scooted over to Rob. Their heads were together - it's possible they kissed, but I CANT confirm. They were definitely snuggle bunnies though; It's possible they may have had a kiss or two. A couple people said that but unsure."

Twitter user @IceAngel34 said, "During the 1st 7min clip, Kristen practically crawled in Rob's lap trying to whisper to him."

During the panel discussion, Stewart, 22, who looked sexy in a green mini skirt and white, cropped t-shirt, and Pattinson, 26, played around with each other, according to Celebuzz.

When walking about the vampire sex scenes in the upcoming movie, Stewart said, "We really tried to make the first one sweet. It's about discovery. Nothing about this series is raunchy."

Pattinson jumped in, telling Stewart, "Get to the point Kristen."

"Shut the f-k up," Stewart said turning to him, which sent a room full of reporters hysterically laughing.

Recently, Pattinson and Stewart were spotted by a number of fans at Nobu restaurant in San Diego on July 11, according to Hollywood Life. They were in town for Comic-Con and reportedly having a romantic sushi dinner.

Twitter user @BrentonLeeRose first reported the spotting as she said, "At Nobu in San Diego and guess who is sitting at the next table. Kristen Stewart and Robert Pattinson."

According to celebs.gather.com, one onlooker said, "They were really enamored with each other."

"They seemed really down-to-earth and low-key," reported another. "They were both really friendly."

Stewart recently saw Pattinson's upcoming film, "Cosmopolis," at its Cannes Film Festival premiere, and she gave her man four stars, according to Fashion&Style.

"He's so good in it!" Stewart told MTV News. "He's really, really [good]. I don't even know how he [did it]. I couldn't even understand it. It's so good; it's so cool, I'm so proud of him. Thank God."

It wouldn't be a surprise when this power couple decides to get married and have some kids. This time, they won't be having half-vampire, half-human little ones. Fans can only hope.
