Old Friends & Enemies to Return to Doctor Who?

Various media sources are stating that Billie Piper, Freema Aygeman and Catherine Tate are set to return the last two 2009 specials (David Tennant's final episodes as the Tenth Doctor) re-portraying their roles as Rose, Martha and Donna. It is also rumoured that John Simm will return as the Master. A media sourced quoted the following:

“This will be the most exciting episode Doctor Who have ever done. We really wanted to get all the 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 Piper to agree is a real coup, but fortunately she loved working on the show so much that it didn’t take much convincing.”

The episodes are due for broadcast later this year on BBC One.
