Like father, like son?

I just read something about the Doctor Who series that maybe I shouldn't have read. Daaaamn. Well, if you're a big fan and don't want to know what the rumors are for season's three finale, STOP reading.
...
Ready?
Well, rumor has it that... Doctor Who has a son.
"Doctor Who bosses have found a way to prevent the much-loved Time Lord from dying out. By giving him a son. ... A source told the Daily Express: 'Since there are only two regenerations left, the BBC needs a plan to make sure the show can carry on. Last year in one of the episodes it was hinted that the Doctor had a child following a doomed love affair with someone from a forgotten planet. Russell will unveil his big bombshell that he really is a dad in next year's series finale."
How true is this? Outpost Gallifrey think it's nonsense. Guess we'll have to wait and see!
