BYE BYE BILLIE. It's with very sad heart (and suicidal hormones) that this Doctor Who geek announces the impending departure of Billie Piper as Rose Tyler on the current series of Doctor Who. It was just announced by the BBC that this current season will be her last. I'd just like to say that, along with Christopher Eccleston's now classic performance last year, Billie Piper has been a major reason why the show has been a success (with acting chops equal to anyone appearing on the show. She will be replaced on the show as the Doctor's companion by former Crossroads actress Freema Agyeman (who will first appear in the final episodes of this current season fighting the Cybermen along with David Tennant & Billie Piper). Best of luck to her but, as with Christopher Eccleston, Billie Piper will not be easy (and probably impossible) to replace.
