Billie Piper is set to return to ‘Doctor Who’ for David Tennant’s final episode.

The actress will reprise her role as Rose Tyler to join the Time Lord’s other companions - Donna Noble, played by Catherine Tate and Martha Jones, played by Freema Agyeman - to take on the Doctor’s arch-enemy The Master.
The episode will see the Time Lord regenerated into new Doctor Who Matt Smith.
A source said: "This will be the most exciting episode ‘Doctor Who’ have ever done. We really wanted to get all the former companions back on board as a fitting send-off to David. And of all the enemies for him to face in his final episode, it makes sense for The Master to be the main one.
Getting Billie to agree is a real coup, but she loved working on the show so it didn’t take much convincing."
Matt Smith will take over as the new Doctor, ending Tennant’s four-year stint as the Time Lord.
Meanwhile, Billie recently joked she christened Tennant "David Ten-Inch" after hearing the intimate details of his manhood from a friend.
