The BBC has confirmed that the pair, who portrayed the 10th Doctor and his assistant Rose Tyler, will both feature in the programme's half-century celebratory episode, which is set to air on November 23. Actor John Hurt is also set to feature in the episode.
Tennant starred in the show from 2005 - 2010, while Piper first appeared as the companion to Christopher Eccleston's Doctor but quit in 2006, although she did return for a number of episodes in 2008 and made a one-off appearance in Tennant's final episode.
Matt Smith, who currently plays the Time Lord, has said that fans "will not be disappointed" by the 50th anniversary show" and promised that it "manages to pay homage to everything - and look forward". He added of the script: "I read it and I clapped at the end. I think it's hilarious, it's epic and it's vast." You can see a trailer for the episode by clicking below.

The Bells Of St John will see Smith joined by mysterious new assistant Clara, played by Jenna-Louise Coleman, who has appeared in previous episodes including Asylum Of The Daleks, and the Christmas special The Snowmen.
