Rob has been charting the Sun's obsession with who'll replace Billie (once can I certainly understand; they'd better not screw this up...), and this is what david-tennant.com has to say...
The above photo shows the Doctor with the girl who is rumoured to replace assistant Rose Tyler as his TARDIS companion.
Adeola, played by actress Freema Agyeman, will appear in the last two episodes of the current series, Army Of Ghosts and Doomsday.
She is rumoured to work for Torchwood and she will help the Doctor battle the Cybermen as Rose bows out of her time travelling adventures.
There has been no official word on who will be the new assistant. But reports in today's News Of The World state that Captain Jack, played by John Barrowman, will rejoin the Doctor as he struggles to come to terms with Rose's departure.
Filming of the new series starts later this summer.
Yay for Captain Jack's return! Freema, by the way, has appeared in The Bill, Casualty and Silent Witness, but then so has everyone...
