The BBC have now confirmed that the Tenth Doctor David Tennant will star in the 50th Anniversary episode of Doctor Who!
The news leaked earlier today thanks to a mistake in the distribution of Doctor Who Magazine, which saw subscribers receive their issues 5 days early, forcing the BBC to issue a hurried press release. Tennant will join current stars Matt Smith and Jenna-Louise Coleman in the special episode.

Also joining the cast will be the Ninth and Tenth Doctor’s companion Billie Piper.
