SOURCE: Tennant & Piper are back for the 50th!
Blogtor Who is reporting that next week's Doctor Who Magazine will confirm that Billie Piper (Rose Tyler) and David Tennant (The Tenth Doctor) have been confirmed as being part of the 50th Anniversary Doctor Who special, which will be 90 minutes long and filmed in 3-D. Actor John Hurt (perhaps most famous for his role in Alien) will also be appearing.
So... here's the big question. Will it be Rose and the 10.5 Human Doctor Clone from the parallel earth? Or will it be Rose and The Tenth Doctor from some point during Series 2? Or will they be appearing as completely new characters?
UPDATE: The news was confirmed by BBC Entertainment Reporter Lizo Mzimba on Twitter.
