Robert Pattinson and Kristen Stewart reportedly avoid public displays of affection, so that their relationship stays a secret from the media.

Twilight insiders have confirmed that the pair are dating, but don’t even hug in front of friends in case word gets out.

“Yes indeed, they are a couple,” a Twilight insider told E! News. “Rob and Kristen do not even show public displays of affection in front of their friends because they do not want to be talked about.

“The only time you see them being affectionate towards one another is when they are doing a scene together.

“Aside from that, one could still assume they are just friends, and that is what they want outsiders to continue believing.”
