In the past, Joe has always known the show's line-up before the general public - but after a major blunder, all presenters of the spin-off show find out who will be heading down under at the same time as the rest of us!
Revealing all about his gaffe in a This Morning interview, Joe revealed that he'd ruined it for himself and the others, "They used to tell us in advance so we could do a little bit of research, and I told my nan.
"My nan lives in Norfolk and she went to the local coffee shop and some geezer bumped into her and started asking her questions. She told this fella everything and he worked for the Norfolk Gazette and it whittled down and they found out it was me."
That is the WORST luck - fancy revealing some TV secrets to someone in the queue at Sainsbury's, only to find that they work for the newspaper...
