Robert Pattinson Can't Lie. Sweet Boy.

KStew gushed about her "Twilight" love interest's honesty to GQ, and Pattinson agrees:

Stewart says Pattinson's honesty is his best feature.

She tells GQ magazine, "He can’t lie. It makes things a little scary for him sometimes. But it's my favorite thing about him."

Pattinson added, "I just say the first thing that comes into my head out of nervousness.

"During interviews I'm literally shitting my pants. I don't want there to be a silence, because I'll start crying."
