"It was my best friend's birthday. We stop by and all of a sudden there were people spray-painting and then I got a lesson on spray-painting from Justin Bieber and he's really lovely and he's really nice, completely different than the media perception. And then I really sat back and thought, 'He ain't half as bad as I was at his age, so he's all right.'"
