Billie Piper talks Who

Billie Piper (mmmmm, Rose) was recently interviewed by the BBC and talked about Rose. Why would she do that now? If you don't know, then I suggest clicking away to some site somewhere where they've never heard of Doctor Who. She uses enough British slang in the interview that I'm not exactly sure what she means all the time. I guess I wasn't in England long enough to learn the language. Cheeky monkey.
