Fable III Voice Acting Proposition, in Development?

BAFTA presenter Jonathan Ross apparently doesn't realize that video games shouldn't be discussed until they're announced and that his Twitter updates can be seen by the world, because he's revealed that Lionhead Studios has approached him to do some voice acting on Fable III.
Goodnight all. Must go to bed. Got asked to do voice in Fable 3 tonight. Subarashi. Oyasuminasia. Woss out.

...

yes they are doing it. Charlie Brooker said he would do a voice for it to ! Great fun !!

Later, he covered his tracks while also sounding ever-so-slightly insane:
yes. No. there is no Fable 3. I don't know. help me.
Thanks, Destructoid.
