....ok doing a little happy dance....

The BBC has announced that Doctor Who will return for a fourth season of alien mischief sometime in 2008. Writer/executive producer Russell T. Davies acknowledged the additional season order by saying, "Series four is officially existing. I'm very excited, but we have known for ages."

Whilst we are still not sure who will play The Doctor (the gorgeous David Tennant has just finished filming Season Three), what is certain, however, is that Billie Piper, who played the Doctor's companion, Rose Tyler, is definitely gone. She was written out of the series and replaced in Season Three by Freema Agyeman, who plays medical student Martha Jones.

Season Three is set to launch on BBC One on March 31st, but the lovely people at "the Beeb" have just put up two new Season Three teaser trailers to sate your appetite while we await news of just when we'll get to see what looks like a pretty fantastic season.
