Look WHO's Coming Back For The 50th!

IT'S OFFICIAL!!!! The 10th Doctor is back for the "Doctor Who: 50th Anniversary". Not only is the very awesome David Tennant back, but his trusty companion Rose Tyler, played by the fantastic Billie Piper is back too with him.
The BBC confirmed this great news yesterday via their Twitter page, along with confirming that British actor John Hurt will be one of the shows special guest stars. There's yet any other official confirmation as to wither or not any other Doctors will make an appearance, but I'm sure they will because it's been rumored that they will in some sort of a way, plus Steven Moffat has said that it would be interesting to see the oldies back on the screen.
