Seriously. I've never come across a celebrity interview where it genuinely felt as if this was so completely the real person, and yet, every interview of Billie Piper's (print or video) feels that way. It reads/sounds like she's just talking to a friend. She is a great actress and all, so it's possible that it's still a bit of a mask, but in her case, it just doesn't feel that way. She comes across as so real, so unpretentious, so vivid and funny, and wise and utterly über, completely awesome!
