Mirror rumors

Dr Who monsters in the know??

Do the Ood know something we don't? Seems to me the aliens will drop a clue about the future of David Tennant as Dr Who in this Saturday's episode.

One of the monsters - talking through a mouth full of tentacles - asks the Doctor to sing with them and, when he declines, says "I think your song must end soon."

My sources say the Time Lord regenerates in the Christmas 2009 special. But maybe the Ood know better...
