Catherine Tate and Freema Agyeman also making comeback
Billie Piper will reprise her role as Rose Tyler and Catherine Tate, 40, and Freema Agyeman, 30, will also be back.
‘This will be the most exciting episode Doctor Who have ever done,’ a source tells The Sun.
‘We really wanted to get all the companions back on board as a fitting send-off to David.
‘Getting Billie to agree is a real coup, but she loved working on the show so much it didn’t take much convincing.’
David, 37, will be replaced by Matt Smith, 26, at the end of the year.
Billie, 26, starred in two series of Doctor Who and returned for a short stint last season.
