Some celebrities are a little cautious around their screaming fans because, well, they don't want a fan to accidentally scratch them or do something inappropriate while trying to get their attention/autograph. Robert Pattinson, on the other hand, is afraid for a whole different reason: he's apparently worried that there's a chance he may be infected with HIV should a fan approach him with an open wound and ask the star to suck their blood.

 
Speaking to News Of The World, Pattinson revealed his fears, saying, "People ask me to bite them and want to touch my hair. I just don't want someone to have a needle and give me HIV and I don't want to get shot or stabbed." The Twilight star went on to talk about one such incident where a group of girls approached him bleeding from their necks. Pattinson adds, ""They were like, 'We did this for you'…I didn't know what to say — 'Thank you, guys?'"
 
People forget that underneath the mysterious Edward Cullen persona there's a real dude named Robert who's just like me and you. So if you see him out in public, chill out. Don't cut yourself open because, um, reality check – he's not a real vampire. He just plays one on the big screen.
