The pair shot to fame as onscreen lovers in the Twilight franchise, and are reportedly dating in real life.
And even though they have become fantasy fodder for teens all over the globe, actress Justine Wachsberger reveals they are both still shy and unassuming.
The star, who plays vampire employee Giana in The Twilight Saga: New Moon, tells OK! magazine, "They're really normal and down-to-earth. They don't think they're superstars or anything. Rob is really nice... He's really a gentleman, he's really sweet, he has great manners, he's funny, but he's shy. You would think that with the notoriety that he's gotten that he's pretty outgoing, but he's actually really shy but really nice and low-key.
"(And Kristen) is down-to-earth, she's not one of those girls who is trying so hard to fit in. She is who she is. She's saying, 'You either like me for who I am, or you don't'. She doesn't fit into that Hollywood mould."
