During the interview on Wednesday morning, Mary happily recalled the names of three bakers who had been sent packing - forgetting that episode three has yet to be screened.
And don’t worry, if you really want to know who leaves ahead of tonight’s show, we’ll give you plenty of warning.
Speaking to Mary about the show, Chris said, “You’ve already lost two, you don’t hang around do you Mary?” Berry replied: “Wait a minute, we’ve already lost three”.
She then listed the names of the contestants she believed had already left: “We lost Marie last week, [REDACTED], and on the first week it was the lovely chap with his little hat on."
Cue Chris hastily steering the conversation in another direction - and total silence from Mary.
And it didn't go unnoticed by ‘Bake Off’ fans who were listening...
Despite Mary’s blunder, she did reveal that this week’s 3D show-stopper round is one of the greatest the show has ever seen, describing it as “absolutely amazing”.
MAJOR SPOILER ALERT! If you don’t want to know who leaves tonight’s ‘Bake Off’ tent then leave now! For those who do... scroll down underneath the gallery below to find out (but don't say we didn't warn you).
