Is Catherine Tate in The Day Of The Doctor?

Short answer - probably not, no.

But a chap with the implausible yet undeniably badass name of "Flight Risk" (thanks, Mum and Dad...) has posted a picture online that allegedly shows a page from OK! Magazine (a publication that manages to sound both manically enthusiastic and sadly realistic about its quality in one two-letter title) that would indicate otherwise.

He scribbled his Twitter name on there, because while the name "Flight Risk" may not seem too trustworthy, a man called "@teprometo13" is a guy you'd leave in charge of your newborns...

There are several reasons to doubt this: first off, the wording is oblique enough that it could well be saying that the "occasion" - ie the Fiftieth weekend - sees the return of Catherine Tate: she could well just be a talking head in a documentary or something. You'll note that we don't see any of the actual interview in this picture. Secondly, if she really were in the episode, and the BBC had kept it such a strict secret, would she really be doing press interviews about it? And thirdly, well... not wanting to stereotype, but OK! is a magazine aimed exclusively at the sort of bored middle-class housewife who gather in flocks to hang around magnolia living rooms eating yogurt and talking about their poop habits. It's not the sort of publication you'd imagine would get their hands on the biggest scoop about the episode yet.

Doctors who can help you lose weight in five easy steps are more their sort of thing...

But, hey, it's something to talk about while we wait for the missing episode press conference...

The Day Of The Doctor will air worldwide on November 23rd.
