Fans of The Great British Bake Off were not OK tonight following Peter's confession.
Tonight, Paul Hollywood and Prue Leith cranked up the pressure on the remaining contestants with three tricky challenges for dessert week.
The bakers had to create a miniature version of a classic cheesecake for the signature, followed by a technical that dates back to the 17th century and a show-stopping jelly art dessert cake featuring delicate sponge.

But as Peter was preparing for the cheesecake task, he made a shocking admission - watch the video above.
Explaining his lime and ginger cheesecake, Peter said: "You can't trust a cheesecake, I have an aversion to cheese in general."
Fans were devastated by his comments, with many taking to Twitter.
